In reply to 02Pilot :
This is a good discussion to be having; it drives to the heart of WHY college is expensive, rather than simply complaining about it or figuring out band-aids to deal with it.
Agreed that the demand for a bachelor's degree has gone up. Demand goes up, supply goes up more slowly so price goes up.
It used to be that houses (or land, property, whatever) was only available to those who could pay for it. The 30 year mortgage wasn't always a thing. But, when it became available, guess what happened to the cost of real estate? As my grandfather used to say, they aren't making any more land.
Back to education....it's an interesting spot that we're in. The original intent of higher education, as you point out, was not necessarily economic advancement. It was education. But now with the "democratization" of higher education - availability of funds to pay for it, at whatever cost - I think the natural demand now is that the "consumer" get something for their money.
On a GRM level, it's sort of like someone having money to throw at a project car, which provides enjoyment beyond the basic purpose of a car as a transportation tool, versus someone shelling our $400 per month for 4 wheels and a seat that has to start and run Every Single Time to get them to their job 20 miles away or they'll get fired. So, everyone's got a car now...but what's happened to cars?
I've read articles (usually written by professors or others in academia) about how the "purity" of higher education is suffering at the hands of the beancounters. Sound familiar? We need to be realistic. Higher education serves a purpose. What that purpose might be varies from person to person, and is dependent upon how much they're willing to pay for it. The problem is we've got a bunch of 18 year olds being shuffled into the equivalent of buying a 1980's supercar project when what they really need is a 2018 Corolla. The supercar projects will still be out there for those with the desire for them and the ability to pay for them.
EDIT:
You wrote: "Now the numbers have swung the other way, or are at least moving in that direction, making for an ostensibly more equally educated society (this is hardly the reality, but that's another topic). But because the economic circumstances of college students are still widely divergent, many of those who attend today are saddled with large debts that ironically work against their primary (and incorrect) expectation that a college education will bring them prosperity."
The reality, it seems to me, _is_ this topic- as you stated, the cost of the education, the debts, all of that- works against the ACTUAL primary goal of the education. Someone staring down the barrel of 20 years of debt payments is thinking, I damn well better get something out of this that will get me a damn good job, and is focusing on that. Meanwhile, the kid with the free ride or the means to pay for the education up front with little worry about the money has the luxury of education for education's sake.
