I see many instances of the reverse of what you are talking about.
First Gen college students who major in “Forensic Science” thinking they’ll become a medical examiner like they see on TV. Their parents are then gobsmacked to learn that becoming a medical examiner in their state requires an MD (i.e. the kid majored in philosophy or history while taking the premed requirements)… Or the kids majoring in Criminal Justice and the parents assume they’ll be fast-tracked to a legal career, kids studying Sports Management so they can become a “famous” agent representing NBA players, etc.
Agree that anyone can get up the learning curve on today’s labor market with enough time, will and research skills. But if you don’t know anyone who is an actual attorney, or has gone to med school, or works with major league athletes AFTER law school and several years as a grunt at a talent agency, it isn’t obvious what it takes to get to where you want to go.
Much easier for a college educated parent to do the legwork on “here’s what it takes”.
