This is the least surprising chart ever.  In a modern society, intelligence is a key driver of success.  Intelligence is also highly inheritable.  It would be shocking if more successful families didn't have smarter kids who would do on average better on a test of intelligence like the SAT....

I wondered if somebody would bring up the idea that causality is confounded by intelligence.  So here is the thing, general intelligence (as measured by IQ) is actually a woeful predictor of wealth:

"Using the NLSY79, which tracks a large group of young U.S. baby boomers, this research shows that each point increase in IQ test scores raises income by between $234 and $616 per year after holding a variety of factors constant. Regression results suggest no statistically distinguishable relationship between IQ scores and wealth. Financial distress, such as problems paying bills, going bankrupt or reaching credit card limits, is related to IQ scores not linearly but instead in a quadratic relationship. This means higher IQ scores sometimes increase the probability of being in financial
difficulty."
