Maybe film students should be like Sam Bankman-Fried

With all that money, he could have done anything.

They make it sound so easy. I read an article somewhere saying that other youthful "Effective Altruism" believers have gone into fields where they could make as much money as possible.

I have two brothers who are jazz musicians. Somewhere, one of their friends, noting some of their other friends, said that a spouse with a lucrative career was the musician's best bet.
 

Maybe going into a field where you can embezzle billions before you're 30 would be the best way to fund your absurdly expensive filmmaking hobby.

How many people become movie directors by studying to be movie directors? Most of them seem to go into it by way of some other career. Actors, musicians, stuntmen. I know of one animal wrangler. Bigfoot researcher, comedian, novelist, screenwriter. I heard of a law student in the South who bought an old movie theater in a small town for almost nothing, then made a movie so he'd have something to show. There was a school principal who made educational films. Evangelicals. Anti-Communists. 911 truthers. Guy who thought Michael Jackson was innocent. Newspaper columnist. 

What's the best field to go into if you want to parlay it into movie directing?
