For the trades (car mechanic, plumber, welder, etc.), no, you don't really need college. For many other occupations, either to land a job in the first place or advance within the organization, you do. Where some people go wrong is going after a degree that has nothing to do with their prospective occupation. Sure, if you want to MINOR in transgender studies, basket weaving or something, have at it, but you'll be lucky, with whatever job you wind up getting, to even pay back the loan.
