1) Why do you think their circumstances will change once they're in University?

2) There is the assumption that the environment in which you grew up in does not permanently affect the way you learn, while many studies have proven this to be untrue. The most critical years shaping the way you learn is in the younger years. Once you're past that, there is no way you can "make up" for it just by going to a better college.

A radical solution I believe is to completely subsidize all education and child rearing costs, such that every child will at least have the necessary basic conditions needed for them to excel. Of course, parents are always going to try and give their kids an edge, but at some point there'll be diminishing marginal returns. To relieve pressure on governmental funding, another radical idea is to couple this with an upper limit on the number of children you can have, so people will not "overburden" the system by having too many children.

1) For most selective colleges, they'll be living in a different neighborhood or different city, in a college dorm instead of their house, with classmates instead of parents & siblings. So almost everything is different.

2) Sure. Environment has both short-term and long-term effects. So a fraction of the environmental effects wear off. I dunno what the fraction is, but when you do the regression to find the weighting of SAT test score and adversity score that best predicts college achievement, it should find the right balance.
