At the same time my Father came from a traditionally wealthy family. While we were not wealthy, his family consisted of successful lawyers, doctors, and entrepreneurs. So there was a lot of pressure to choose a somewhat preordained path to success.
A therapist encouraged me to focus on my own independence in young adulthood, including standing up and being more assertive with my parents. So I really blossomed much more in college choosing my own path away from my parents.
All to say a lot of what happens is parents have kids for their own needs, and end up neglecting who their kids are and want to be. How much here is American cultural issue? How much is a problem in all cultures? Certainly you see other notably workaholic cultures really put this pressure on kids to succeed and focus on serving the older generation.
