How much of that is due to having more knowledge, and how much is classism? i.e. having upper class parents is probably a very high return aswell.
Also that only really works once. If spent 40 years, doing 10 4 year degrees, by this logic, I'd be a multibillionare right? Something is wrong with this theory.
"having upper class parents is probably a very high return as well"
True, which is why the studies account for factors such as family education and family income in order to attempt to isolate the impact of the one factor being measured: the subject's education level.

I can't imagine that the authors claimed anything more than that.
