I'd almost venture to say "tens of thousands of dollars of debt (sometimes hundreds of thousands)"
A bachelor's degree serves as a barrier of entry for many roles outside of IT. Historically the pay gap between the jobs you can get without, and what you make after clearing this barrier, made up for the initial investment rather quick. Now that there are diminishing returns on that investment, you need to optimize on a case by case basis. Does your chosen profession allow other paths to high paying jobs? Can you get the degree with less investment using less costly credit hours (community college first, then state university)? Is the peer group and the resulting network formed after attending college valuable enough to boost your career 5 years later? There are not that many well paying jobs accessible without a degree, I think cost optimization is worth it in the long run instead of not going to college at all.
Berkeley was my guess for an expensive in-state tuition rate and they're $38k for 2 years.
Unless you're including housing/food/etc.
It's also hard for me to include housing because you'd need housing no matter what path in life you choose.
Rauner cut 400 million for education during a year he could make a budget with legislators.
Pat Quinn cut education spending by 340 million during a year when he got to write the budget himself because the legislature couldn't pass one.
the confounding factor for young adults, i suppose, is that it's hard to be certain enough about future interests amid all the possibilities not yet forgone to stay the course without (understandable) alteration (i changed course a few times in college myself).
But there’s another aspect to college — the friendships, the discovery, finding interests, finding yourself.
These aspects have gone to the wayside, because for the majority of people there’s just not enough money to justify this. It feels similar to the cuts to art and music in lower schools - “what good are those programs for getting a job?”
On the other hand, if you want to be an engineer then it's pretty important to go to a reputable institution - at least in the field I work in.
