Id certainly believe that it's possible to do so. However, in the same way that anyone could be president, not everyone can be. Lots of colleges don't even have enough jobs in the area to support every student working, and the number of hours you'd have to work can prevent anyone with a difficulty major from doing so

This doesn't make a lot of conceptual sense. If 100,000 people move into a town of formerly-3000, they will severely outnumber the open job slots from before they moved in, but that doesn't mean no work is available for any of them. Most of them will find work just as most people everywhere find work.
Work is available to anyone who can do something productive.
Some US based acquaintances recently discussed the college options and choices of their kids.
A year at the cheapest college they discussed cost more than twice (tuition, without a room) as much as my German B.Sc. and M.Sc. combined: that is, 5 years of study (or longer - I decided to study part-time and earn real money in parallel. It costs little extra).
