College attracts more followers and supporters, also improves his Youtuber skills.
If he learns business economy and marketing he learns to really talk to his target groups.
What exactly is your son passionate in, what does he presents on Youtube?
Find a University & faculty discipline which is supporting this, instead of putting force and foreign determination onto him. He doesn't want's to be you nor does he wants to live the life you chose and predefine for him, otoh he appreciates your help. Did you ever helped him with his passions?
Your son isn't named Van Wilder? Per pure chance?
Son:
Go for Berkeley, Stanford, Massachusets or Harvard and your Dad will regret his shoice,
when he gets the bills. Then you can also study Jura and later you file a lawsuit against your dad and your mom, for sadomasochistic psychic violence and mental cruelty ( yes that's a real thing in the US). If you also study Psychology and Philosophy you can make it a big time rip off and your parents will financially never recover from that move. Plus you get the house if they are in jail and debt.
Then this will also fulfill its function as your magnum no. 1 and if you make it into the news,
you will get a lot of clients. These expect from you to do the very same with their parents and together with the gained userbase from youtube and your youtube experiences and boatload of advisories and other videos, this will get your opus magnum then.
