Ah, assuming a profit of $500 does make the maths make sense.

But $500 profit a year from a single customer is way above the average for the majority of businesses.

So it follows that the majority of businesses does not make trillions of dollars either. :)

Still, there are several businesses that are making on average over $100-500/year profits on me. More or less my bank, car maker, gas station, energy company, furniture store, favorite soda brand, supermarket, fast food chain... what else? Scary thought.

Your bank might not be. They are often just acting as a middle man and lending money to you that they borrowed from the bond market, taking the spread as their admin expenses.
