What carrer does not take much time in school but makes lots of money?

Question

like maybe just a 4 year college

Answer 1

When you go to college, you need to take an economics class.

If there were something that everyone could do easily that paid a lot of money -- then lots of people would do it.  This would create a surplus of people doing that thing, and salaries will fall.

There is no free lunch.  You need to do the work to get the high paying jobs.
