I currently work in Outside Sales, even in this industry, they look for a degree...it's sales, ridiculous. I'm not that excited about my degree, however statistically you can a have better job.
Nevertheless, I would say it depends how hungry you are, if you are TRULY going to run after investing and waste no time. Then chase your dream, if not, school will by default get a little better paying job but it honestly it isn't a land slide. There are some brass knuckles jobs that will pay more than the average professional job - i.e. the oil field or any manual labor type of job, or even a trade and you will make some descent money as an employee and have minimal expenses to surpass with passive investments.
At the end of the day, it is going to depend on your dream. You will save a lot of money not going to school, but if you are going to lazy in chasing your dreams, then it would better to go to school and pursue investing while you have plenty of time in school.
I hope I made some sense there.
