I'm sure I will be downvoted for even mentioning his name, but Charles Murray has been writing about this for decades.
He also strongly argues that your ability to succeed is a measure of your innate intelligence. (perhaps this is the part that user/yasp thought would be considered abhorrent?) and that combines with the earlier parts to say that there will be increased stratification and it will be on intelligence as well as on money.
This whole thing is a waste of time because I gained nothing novel from having chased this vague-ass comment. Ugh.

Maybe edit or reframe your comment.
And it would be helpful if the commentary on Murray's thoughts exceeded the meta-commentary on mentioning Murray's name.
