>that most people don’t receive education how to do that properly.

Incentives matter far more than education; parents have a built-in biological incentive to care for their children, so on average they put in more effort, that's why children at orphanages do so poorly, and homeschooled children do better on standardised testing than public schooled children.

This is a good point. You probably heard people complain about "Asian parents," but could it be that those "Asian parents" were actually good?
