The Bell Curve (1994) talked about the intellectual stratification that is happening in society. The author and resulting research was called "racist" and has been shouted down time and time again but much of what you say is discussed in the book. He shows correlation between intelligence and [income, parent's socioeconomic status (SES), job security/unemployment, educational attainment, and tons of other things]. The data is sporadic pre-WW2 but complete and well-validated afterwards. He avoids drawing conclusions or prescribing solutions.
All of it is interesting and some is compelling, but the book is generally forbidden to be discussed in "polite" company.
The interesting thing about the book.. to reduce the "racist" attacks, the author only looked at white people throughout the bulk of the book.
