Or maybe it's not so simple, and IQ can also be changed by environment. It's not a crazy idea that people with more money have better access to education.

And people with more money have less kids. So more intelligent people have less kids, more intelligent people make more money, can spend more to develop those fewer kids' educations, so you have an ever decreasing amount of 'smart' kids and thus the average IQ goes down.

IQ being highly hereditary doesn't mean that it isn't also influenced by environment.
