Denying that intelligence has a hereditary component doesn't make it so.

Of course this doesn't mean that every smart couple will birth nothing but smart kids nor that every stupid couple will birth nothing but stupid kids.

But lets say for the sake of argument that if 90% of all births to 2 intelligent people result in intelligent children, while only 10% of births to two stupid people result intelligent children... the guy would have a point, that meeting your spouse in college could result in a widening gap of intelligence.

Hereditary aside, more wealthy parents are likely to be able to expose children to good things (a home full of books, a good home environment, a good school, etc.), while more poor parents will be more likely to expose children to bad things (crystal meth, alcholicism, bad schools, like of importance in education).

Not if the guy or his spouse made it to college by affirmative action.
