If by college you mean that he wakes up at 5:30 am and goes to college then and doesent finish college till 11:00 pm then the parents should let him go to college. If he would be one of these college fakers that just sits and says they are in college yet they are just busy on their cell phones the whole day and just go there for socializing purposes then he should go get a Torah education.
I have no problem with people who can’t learn so they want to go to college, but let them do it seriously! And not waste peoples tuition.
