There’s a chart here of the amount of money people make based on personality type….
Granted, it looks like a wide disparity, but it seems to be about $30,000 difference per year, after taxes, that’s not big.
What I find interesting is that extraverts earn more money. Extraverts by definition need more stimulation in life… etc. so they want to go out on the town more etc. etc. etc. introverts are content staying at home with a good book… so… the people that prefer a more spendy lifestyle by their nature make more money to support it.
This sounds like a zero sum game.
Why does the American dream push for wealth?
