All universities being private? Jesus, arg-anon. That isn't even remotely true. The huge majority of universities here are Public, and while you have to pay to attend, more often than not, any half-decent student can do it for close to free (if you make non-retarded decisions).
For instance: I went to my local accredited university for around $5k a year. Payed for it with a mix of loans and out of pocket while working part time. Graduated with a CS degree, and now 4 years later I'm making roughly $100k a year with around $13k left in student loans.
I only ended up paying for college because I was lazy in highschool and most of my college career as well. In Georgia (where I live), any student that does even decently well in school gets a scholarship that covers most of the cost of their college tuition (if they go to a Georgia school). I didn't have this, but I knew plenty of people that did. When you read about idiotic millennials getting hundreds of thousands of dollars into debt for college, it is because they made stupid decision after stupid decision with absolutely no foresight or planning.
As far as the 2-year degrees are concerned: those are a mixed bag. It is possible to get a 2-year degree and come away making decent money, but it is also possible to get one that is a complete waste of time. I think the biggest takeaway about the American higher-education system is that it rewards those who plan and are smart about their decisions, and severely punishes those who are just chasing a "college lifestyle" or whatever. And as for those people, they can fuck right off.
