True. But logic works. A single negro baby momma that can barely speak English who lives in the ghetto with three children isn’t going to have well educated children. Compare that to a college educated mother and father who actually cares about education and you have an entirely different situation. Groomer teachers certainly don’t help. Most are low IQ’d, are barely educated and literate. Parents make all the difference.
Research has actually seemed to show that that correlation is minor compared to other factors.
