I know plenty of people benefiting from the stock market with average and less than average IQs. This is a matter of classism not intelligence. If you have enough money to invest your benefiting, and the more money you have to invest the more you are benefiting.

Of course, there are a few outlier founders, CEOs, and stock traders that are benefiting much more then average. What separates these outliers from others isn’t IQ, because there are plenty of people with very high IQs that are doing about average economically.
