alt Hacker News> wealthy parents tend to be wealthy because they are more intelligent
Not "more intelligent", just "unusual in some way". People can be wealthier than average for all sorts of reasons unrelated to intelligence (as defined by IQ). Here's a sampling of them:
Being social and good at sales. Most successful real estate agents I've met don't strike me as particularly brilliant.
Working a boring job, living modestly, and investing in index funds for 20 years.
Winning the lottery (either literally, or by accidentally buying something cheaply that turned out to be worth a lot)
Marrying rich and divorcing.
Inheriting wealth.
Being a successful athlete or entertainer.

Intelligence correlates highly with not having anti-social behaviors.
So a lot of the time, it's not "being smart" that carries you to wealth, its avoiding the "disastrously stupid things" that stops you from being poor.
A lot of those correlate with intelligence and “grit.”
Being good at selling to people absolutely requires intelligence. So do many entertainment fields, and athletic achievement more than you might expect.
Investing consistently in an index fund over 20 years requires a bit of intelligence and a lot of grit.
