Back when you could work 20 hours and survive, and tuition at a state college was $200 a seamster, it made sense to get a degree, or at least, it wasn't something you got deep in depth with. I left college without owing anyone a dime. I paid my own way in grad school. Few without parental support to the max or scholarships can leave college without being fairly deep in depth. A job delivering pizzas 5 nights a week will not pay the bills like it did in college.
My roomie was a clerk in a grocery store, another drove a school bus, and my ex was flipping burgers at the local burger joint. After we married she was proofreader at a local paper while finishing college. All were paying their own way for the most part with parents paying the $200 tuition and maybe a few bucks along to buy gas and snacks. It didn't break anyone's bank. A parent shelling out $100k for even a scholarship student is financially hurt as well as seeing their child deep in debt.
