> However, the research suggests that having the genes for school success is not as beneficial as having parents who are highly educated and wealthy. Only 47% of children in the study sample with a high genetic propensity for education but a poorer background made it to university, compared with 62% with a low genetic propensity but parents that are more affluent.
TLDR: being born to a rich family matters more than anything innate as far as educational success.
This is a great sales pitch for free college, at least for the poor.
