The fantastic book[1] The Haves and the Have-Nots: A Brief and Idiosyncratic History of Global Inequality by Branko Milanovic points out that the 3 most-important correlated determinants of financial success in life are, in order:
1. Geography (which country you're born in)
2. Parents' finances
3. Your gender
These 3 explain the vast majority of the variance in income between people. Knowing these 3 facts about a person allows you to predict their income with high accuracy (small 90% confidence interval).
