@Much2learn From my view:
Lower class parents are nearly 100% hands off when it comes to anything school related.
Middle class parents put a lot of money and time into sports, period. My theory is short-term glory of sports success (my kid won the summer championship!) is more pleasurable versus the long-game, delayed gratification of academic success (my kid became a lawyer in 2024!).
Wealthy parents put a lot of money and time into sports…and into living in premier district (or private schools), musical lessons, tutors, summer programs. Big picture planning and grooming.
