The "Hustler Professor" Who Shut Down Napoleon: Why J.B. Say is Your New Business Hero

If you’ve ever felt like the system is rigged against you or that the world is running out of opportunities, you need to meet Jean-Baptiste Say (1767–1832).

While other economists of his time were worried about the world ending, Say was the ultimate optimist. He wasn't just a guy who wrote about money in dusty libraries; he was a rebel, a factory owner, and the man who turned the word "Entrepreneur" into a superpower.


J.B. Say is Your New Business Hero

1. The Birth of the "Entrepreneur"

Before J.B. Say, economists talked about "Labor" (workers) and "Capital" (money) as if they just mixed themselves. Say realized something was missing: The spark.

He was the first to identify the Entrepreneur as the most important person in the economy. He described them as the "agent" who moves resources from a place where they are worth little to a place where they are worth a lot.

The Human Example: Think of someone who sees a pile of discarded fabric and a group of talented tailors. That person doesn't just see "cloth" and "work"; they see a brand-new line of Streetwear Hoodies. Say argued that without that "Hustler" vision, the cloth and the tailors would just sit there doing nothing.


2. Say’s Law: The Engine of Growth

Say’s most famous contribution is "Say’s Law," which states that "Supply creates its own demand." At first, this sounds confusing. Does it mean that if you make 1,000 bad products, people will just buy them? Not quite.

The "Smartphone" Logic: Say argued that when a company produces a new gadget, they aren't just making a phone; they are distributing wealth.

1.     The company pays the engineers to design it.

2.     They pay the factory workers to build it.

3.     They pay the miners for the raw materials.

Now, all those people—the engineers, workers, and miners—have money in their pockets. Because they were part of "producing" the phone, they now have the "demand" (money) to go out and buy shoes, groceries, or even the very phone they built. In Say's world, production is the source of all power. You can't buy anything until something has been made first.


3. The Ultimate Standoff: Say vs. Napoleon

Say wasn’t just a thinker; he had a backbone of steel. In 1803, he published his masterpiece, A Treatise on Political Economy. It was an instant hit—even Napoleon Bonaparte read it.

Napoleon loved the book but hated one thing: Say’s belief in free markets. Napoleon wanted to use the economy to fund his massive wars. He invited Say to a private meeting and offered him a high-paying government job on one condition: Say had to rewrite parts of his book to favor Napoleon’s high-tax, pro-war agenda.

Say’s response? "No." He refused to lie for the Emperor. Napoleon was so furious that he banned the book and fired Say from his government post. Say didn't blink. He proved that principles are more valuable than a paycheck from a dictator.


4. Standing on Business: From Theory to the Factory

After being "canceled" by Napoleon, Say didn't go into hiding. He decided to prove his theories worked in real life. He moved to the countryside and started a Cotton-Spinning Factory.

He went from being a "Professor" to a "CEO." His factory became a massive success, employing hundreds of people and proving that his "Supply creates demand" theory actually worked. He didn't just write the rules; he played the game and won.

By the time Napoleon fell from power, Say was a wealthy, successful man. In 1826, his impact on the world was so great that he was awarded a Gold Medal by the Société d'encouragement for his services to the industry. He ended his life as the first-ever Professor of Industrial Economics at the Collège de France.


5. Why J.B. Say Matters in 2026

We live in a world where people are often scared of the future. Say reminds us that:

  • The Entrepreneur is the Hero: Whether you are starting a YouTube channel, a tech startup, or a local clothing brand, you are the engine of progress.
  • Production over Consumption: You can't "spend" your way to wealth. You have to "create" your way there.
  • Integrity Wins: Like Say standing up to Napoleon, your reputation and your truth are your greatest assets.

J.B. Say was the "Hustler Professor" who taught us that the market isn't a scary monster—it’s a playground for people with ideas. He took on an Emperor, built a factory, and changed how we think about work forever.


Let’s Talk!

J.B. Say believed that everyone has the potential to be an "agent of production."

  • If you were to start a business today with zero fear of failing, what would it be?
  • Do you agree with Say that "Supply creates Demand," or do you think the customer has to come first?
