The Morality and Practice of Finance

All right, our final class. We’ve been talking about what finance does, and really what finance is doing is allocating capital in the economy by providing a return on saving and by managing risk. Now, this is a crucial function. The world in which we exist today could not exist without it. Indeed, you cannot imagine any level of advanced civilization without finance.
Thank you, guys!
In 1976, Steve Jobs and Steve Wozniak were working on a little project in Woz’s parents’ garage. This project was a personal computer, including logic boards. Wozniak saw it as a fun hobby, but Jobs had already started thinking that there might be a business here. Jobs consulted someone from Atari (a big company back then) and built up a business plan.
Jobs and Wozniak realized they needed money to build a demo. However, they didn’t have much. Wozniak sold his HP calculator for $500, and Jobs sold his Volkswagen for $1,300. With that $1,800, they built the demo.
They then took it to a computing club, and people were enthusiastic. Paul Terrell, who owned a chain of electronics stores in the Bay Area, agreed to buy 50 units if they could build them. However, they still needed more money.
They went to a high school friend’s father, who lent them $5,000. But when they approached a bank, they were turned down. Jobs’ appearance didn’t help much—long hair, unkempt, and smelling of his fruit diet. Still, they went to the electronics supplier and asked if they could get the parts on loan, showing them the commitment from Terrell. The supplier agreed. They built the computers and sold 50 units—this was the first transaction made as Apple Computers.
This story illustrates the importance of capital at every step of business creation. Without the friends and family financing and vendor credit, there would have been no Apple. And without the line of credit secured through Mike Markkula (former Fairchild Semiconductor engineer), Apple wouldn’t have been able to scale.
In December 1980, Apple went public with an IPO at $14 per share. It opened at $22 and closed on the first day at $29. Today, Apple is one of the largest and most successful companies in the world.
Equity represents ownership in a company, and stock is a form of equity. In the early days, Jobs and Wozniak sold most of their shares, leaving them with only a third of the company. The majority was owned by venture capitalists.
Ownership in a corporation means you have control—51% of the shares control the company. Equity holders also have a residual claim, meaning they get what’s left after all debts are paid.
One of the most important concepts for stock markets to exist is limited liability. This means shareholders can’t lose more than what they invested. Without this protection, stock markets wouldn’t exist. Shareholders cannot be personally liable for company debts.
Equity is a key way to raise capital for businesses, especially in the early stages. In the case of Apple, venture capital played a significant role. Venture capital is a form of private equity where investors provide funds to startups, typically in high-risk industries like tech and biotech.
Although venture capital involves high risks, successful investments can yield exceptional returns. Venture capitalists generally make around 10 investments: five will fail, four will offer modest returns, and one will be a massive success. That one success compensates for the losses.
A venture capitalist’s job is to screen companies and determine which ones have a chance of succeeding. They also provide valuable guidance and expertise to help the company succeed. For example, Don Valentine of Sequoia Capital helped Jobs and Wozniak build a business plan and brought in Mike Markkula as the CEO.
Venture capital is especially crucial in industries like technology, where success is uncertain but rewards can be massive. After raising venture capital, companies grow and develop their products, as Apple did with the Apple I.
Private equity and venture capital are both forms of equity funding, but they differ in terms of the businesses they target.
Private equity funds generally target businesses with established cash flow, aiming to increase efficiency and profit.
Stock buybacks are when companies buy their own shares from the market. While some argue that stock buybacks manipulate stock prices, the reality is that buybacks are a way for companies to return excess capital to shareholders when no better investment opportunities are available.
Why buy back stock instead of paying a dividend? Dividends are taxed as regular income, while capital gains (from stock buybacks) are taxed at a lower rate. Therefore, stock buybacks are more tax-efficient.
Stock markets allow businesses to raise large amounts of capital quickly by selling shares to the public. Going public through an IPO enables a company to scale rapidly. The stock market also provides liquidity, allowing investors to buy and sell shares with ease.
Stock markets democratize access to investments. Ordinary people can buy shares in companies like Apple, which was once only available to a select group of wealthy investors.
Stock markets facilitate the allocation of capital across industries. For example, when industries like the Rust Belt decline, capital is reallocated to emerging industries like Silicon Valley. This capital reallocation fosters innovation and growth.
The decline in stock prices signals to investors that a company may be in trouble, while rising stock prices indicate success. The stock market helps investors and businesses make better capital allocation decisions.
Stock prices reflect a company’s performance and future potential. A falling stock price signals a problem, forcing managers to re-evaluate their strategies. For example, IBM’s stock decline in the 1990s forced the company to shift focus from mainframes to services.
The price at which a company goes public depends on the market’s expectations. The investment bank that handles the IPO sets an initial price based on perceived value, but the market’s reaction ultimately determines whether the price goes up or down. Typically, stocks rise after an IPO, but the real focus is on the company’s performance over the next six months.
Corporate taxes often lead to higher prices for consumers and lower wages for employees. Lowering corporate taxes can benefit the economy by increasing wages and lowering prices.
Stock buybacks, while often criticized, are a sign that companies have excess capital with no better investment options. They are a way for companies to return capital to shareholders.
Conclusion
The financial system, particularly the role of venture capital, private equity, and stock markets, is crucial in raising capital, fostering innovation, and allowing companies to grow. While the process involves high risk, it offers the potential for massive rewards and fuels economic development across industries.
So, we’ve discussed the history of usury, interest, and the development of banks. We’ve covered central banking, but now let’s focus on the financial institution we all interact with regularly—the bank. What does a bank actually do? How does it function? How does it make money, and what role does it play in the economy?
A bank primarily lends money to businesses, consumers, and various projects, both for productive use and for consumption. Banks are essential to what’s called consumption smoothing, which is the idea that you can borrow money now (e.g., for a house or a car) and pay it back over time, smoothing your consumption over the course of your lifetime. This allows you to enjoy goods now, like buying a house, even if you don’t have the full amount upfront. For example, most people use mortgages to purchase homes, and this borrowing allows you to live in the house long before it’s fully paid off.
Banks also fund businesses, real estate projects, and infrastructure, enabling the economy to function and grow. However, banks do not lend money to everyone. Selectivity is a critical function of banking. Banks decide who gets a loan and who doesn’t, ensuring that money is directed toward productive, profitable projects rather than irresponsible or unwise ventures.
Banks attract deposits and then lend out most of the money they hold. They make money by charging a higher interest rate on the loans they give compared to the interest they pay on the deposits. Banks hold two types of deposits:
Banks have to manage risk and liquidity carefully. They don’t keep all the deposited money in cash; instead, they lend it out or invest it in securities. This is known as fractional reserve banking—the system where banks keep only a fraction of their deposits in reserve and lend out the rest.
In the traditional fractional reserve banking system, banks only have to keep a portion of their deposits in reserve. For example, if a bank receives $100, it may only keep $10 in reserve and lend out the other $90. This process creates more money in the economy, as that $90 lent out gets deposited in another bank, which can then lend out 90% of that amount. This multiplier effect leads to the creation of more money in the system.
If too many people request their deposits at once (a bank run), the bank may not have enough liquid assets to pay them all, which can lead to bankruptcy. Even though fractional reserve banking increases economic activity, it also makes the system fragile.
Moral hazard occurs when banks take excessive risks because they know the government will bail them out if things go wrong. This happens because of deposit insurance (FDIC), which protects depositors. When banks know that uninsured deposits will be covered by the government, they may take on higher risks than they would otherwise.
Silicon Valley Bank (SVB) serves as a modern example of this issue. It had many deposits from venture capital firms and startups. During the COVID-19 pandemic, SVB began investing heavily in long-term government securities. However, as interest rates rose and the value of these bonds fell, SVB found itself unable to meet its depositors’ demands for withdrawals. This triggered a bank run, and despite the bank’s solvency on paper, it failed because of liquidity issues.
The FDIC and government regulators intervened and bailed out the depositors, even those with more than $250,000 in deposits, creating a moral hazard because it incentivized banks to take greater risks knowing the government would step in to cover potential losses.
The S&L Crisis of the 1980s is another case study in moral hazard. Savings and loan associations (S&Ls) were allowed to invest in a wider variety of loans. They had previously only been allowed to issue mortgages at low, fixed rates. But as inflation increased, S&Ls faced a situation where they had to offer higher interest rates to attract deposits, even though their existing mortgages were still low-yielding. This mismatch led them to take on speculative, high-risk loans that ultimately resulted in their collapse. The government stepped in to bail out these institutions, costing taxpayers billions of dollars.
SVB’s downfall provides a clearer picture of how modern banks can fail due to a mismatch in liabilities and assets. The bank had deposited funds from tech startups and venture capitalists but invested those funds in long-term securities. When inflation rose and interest rates increased, the value of these long-term bonds dropped. When withdrawal requests surged due to concerns over the bank’s solvency, SVB couldn’t meet those demands. The government had to step in, bailing out depositors, creating more moral hazard in the system.
The government has created an intricate regulatory environment, with multiple agencies such as the FDIC, OCC, and the Federal Reserve, tasked with ensuring the stability of the banking system. However, the continued presence of moral hazard means that these regulations often fail to stop risky behavior. While some regulations, like Dodd-Frank, were created to prevent another financial crisis, they haven’t solved the underlying problems of risk-taking in banks.
Banks are central to the economy, but the system is fragile. The fractional reserve system creates money, but it also creates risks, particularly during times of economic stress. The presence of moral hazard, where banks take excessive risks knowing they will be bailed out, contributes to the instability of the system. While regulatory measures have been implemented, the underlying issues persist, and the financial system remains vulnerable to crises.
Next class, we will dive into the stock market, followed by a discussion on financial crises, the fragility of the system, and the future of finance.

The story of Moses freeing the Israelites from Egypt isn’t just ancient history — it’s an archetype.
Egypt = the illusion of success.
Money = the false god.
Maybe Bitcoin is our Exodus — opting out of the system, wandering the desert for a generation until we reach the Promised Land.
But to get there, we have to be willing to:
I lay under a tree and read while gazing at one of the greatest men of history every day after walking barefoot through a garden, and tending the land because the modern world is a distraction and I choose to return to meaning.
Perhaps it’s better to thrive in isolation than pretend in a city of degeneration.

Johann Wolfgang von Goethe is considered one of the greatest men in history because he embodied the ideal of a universal genius — a person whose intellect, creativity, and moral insight reached across the full spectrum of human knowledge and experience. His greatness lies not just in the quantity of his work, but in the depth of his thought, the breadth of his influence, and the timeless relevance of his ideas.
Goethe wasn’t just a writer — he was also a scientist, statesman, philosopher, and artist. He made notable contributions to:
Goethe refined the German language through his precise, poetic use of words. His stylistic mastery elevated German literature to world-class status, influencing writers such as:
In Faust, Goethe captured the human struggle between light and darkness, knowledge and desire, freedom and temptation. It’s a universal story of man’s quest for meaning — the modern equivalent of a sacred text.
Goethe’s vision wasn’t rigidly moralistic. He embraced contradiction and complexity: joy and suffering, reason and emotion, nature and spirit.
“He who strives on and lives to strive / Can earn redemption still.”
— Faust, Part II
Goethe’s influence touches many fields:
Goethe didn’t claim to have “arrived.” He lived as a process, constantly evolving. He studied nature, meditated on time, reflected on mortality, and sought truth through experience.
He coined the term “Weltliteratur” — world literature — believing that culture should transcend national boundaries.
“He who does not know foreign languages knows nothing of his own.”
His life offers an ideal: integrate knowledge, beauty, and action.
Goethe stands alongside figures like Leonardo da Vinci and Plato — people who didn’t merely master one domain but reshaped the way humanity thinks, feels, and creates.
His greatness lies not in a single achievement, but in his fullness of being — the fusion of poet, philosopher, scientist, and seer.
“A man sees in the world what he carries in his heart.”
— Goethe
Maybe worth venerating?

What’s popping, people?
It’s Dante.
Every morning I walk through the park and think:
Where is everyone going?
Where are we all rushing off to today?
The streets of Philly are filled with people scurrying around like anxious, tired bees. Fumbling with their things. Half-asleep. Hungover from a weekend of alcohol and TikToks. Everyone’s in a rush to be “productive.”
And I get it. That’s the world we live in.
But this modern world is deeply unnatural.
Leisure isn’t laziness. Leisure is a return.
A return to what is natural. To what is good.
To what is righteous.
It’s crazy when you think about it—we spend most of our lives inside.
Inside buildings. Inside boxes. Inside systems.
But when I step outside and move my body through open space, I exit the passage of time.
I return to the present moment.
And that’s where peace lives.
When you’re indoors too long, your soul wilts.
But outside? With the sun on your skin and the trees overhead?
You remember.
This world wants you stuck in the past and obsessed with the future.
Crunching numbers. Chasing goals. Locked into a loop.
But the only time you’re truly living is when you’re not striving at all.
This whole system was designed with preset rules.
Work. Save. Strive. Consume. Repeat.
But what if you said:
“Nah. I’m playing my own game.”
That’s what leisure is to me.
It’s refusing to chase modern success—money, fame, followers—because you’ve seen clearly that it’s not worth it.
And it’s not about hating society.
It’s not nihilism.
It’s clarity.
You opt out because you’ve tasted something better.
Because you’ve caught a glimpse of paradise, and now you can’t unsee it.
Leisure takes balls.
To say no to the hustle.
To walk instead of run.
To be still in a world addicted to motion.
It’s not always easy.
You’re going against the grain.
But maybe that’s your superpower.
And when you finally release the need to grasp and strive and prove,
you become free.
You become light.
You become like a bird in flight, dancing from tree canopy to tree canopy.
Purpose comes from putting your feet forward.
Look at the word: purpose — it literally means to put forth.
So every day I walk. I create. I photograph.
And that’s how I move forward.
Photography for me is magic.
It’s my dance. It’s my song.
The light hits the world, and I get to draw with it.
Every street corner becomes a canvas.
And with a camera small enough to fit in my pocket, I stay in the flow.
I move with purpose. I create meaning.
But on my own terms.
Everyone’s got to find their own way.
Nobody’s going to hand you your meaning.
You’ve got to design your life from the inside out.
The ultimate luxury isn’t money. It’s sun on your skin.
It’s:
That’s astonishing. That’s holy. That’s freedom.
As I watch the bees buzzing in and out of their little hive, I think about the idea of productivity.
Why are you so productive?
For what? For who?
You don’t have to be like the bees.
You don’t have to toil endlessly in a system that was never made for your flourishing.
You can be like the bird.
Fluttering. Singing. Dancing in the air.
Light as hell.
Still provided for.
Design a life of leisure. Disregard the rules.
Play your game your way.
This, right here—this life of leisure—is the life worth living.
If the day feels like play,
and the game is just hard enough
so that you consistently have to level up by 1% each day,
meaning is found.
If the day feels like toil,
and the work is just tolerable enough
so that you consistently show up to check boxes,
meaning is lost.

In a modern world that maximizes productivity
and neglects leisure,
you are going to have to find a way
to create your own game.
If the game that is rigged against you provides no meaning,
why play at all?
What’s popping, people?
It’s Dante. I’m walking here through what feels like the Garden of Eden — Fairmount Park, Philadelphia. And I’ve been thinking…
Thinking about this cult we live in.
The cult of productivity.
Everywhere you look, it’s go-go-go. Hustle. Grind. Optimize. Perform.
But me? I’m done with that game.
I embrace a life of leisure.
And no, I don’t mean laziness.
I mean true leisure — otium.
“Leisure is the ultimate virtue. It’s the ultimate good.”
When I say leisure, I’m talking about:
That’s where life begins.
Not in the doing. Not in the striving. Not in the checklist.
But in the being.
We’ve all been brainwashed to think that value comes from accomplishment.
But I’ve found that to live fully, you have to detach.
Withdraw.
And not in some bitter, angry, “fuck-the-world” way.
No.
You withdraw because you see clearly.
You realize none of it — the busyness, the events, the endless grind — holds real meaning.
So what do you do instead?
You spend time with God.
You move your body.
You breathe.
You observe.
You think clearly — because you’re fasted and present.
And you find yourself thriving. Full of vitality. No need for external stimulation or validation.
You just are.
“The ultimate privilege in this modern world is having the sunlight kiss your skin while you have a grin on your face.”
That’s it. That’s the gold standard.
Modern wealth is:
This is the life worth living.
Not trapped in the loop. Not seeking status or rewards.
But just living. Seeing. Moving. Feeling.
I’m not saying do nothing forever.
But I believe in virtuous work — work like this tree here.
Months ago I elevated it. Trimmed it so you could actually see the trunk.
Still getting strangled by ivy, but progress is progress.
That’s the kind of effort I believe in. Real, grounded, living work.
Not clicking buttons on a glowing rectangle for 12 hours. Not optimizing your calendar like a maniac.
Choose otium. Fuck negotium.
I’ll just be chilling.
🔍 What Does “Fiat” Mean?
The term “fiat” comes from Latin, meaning “let it be done” or “by decree.”
So fiat money = money by government decree.
- It has no intrinsic value
- It is not redeemable for a fixed quantity of gold, silver, or goods
- Its purchasing power can be inflated away
