San Jose? I don’t know what an economics degree is good for. Send your son to the local SJCC trade school for a few semesters and learn machining. They work with SJ state which has a great industrial engineering program. (I chose Fresno but anyway...) there are tons of entry level machinist positions that will turn in to very lucrative positions after 4 or 5 years. Contrary to popular belief manufacturing is far from dead in the USA. Problem is its so damned expensive to live in that area. My two cents as a former aircraft engineer that started a machine shop.
Send him to law school. The stuff you learn there is invaluable, whether you practice or not. 50% of lawyers don’t practice, but they can do ANYTHING they want, start businesses, be executives, etc.
