This makes absolutely no sense when you spend two seconds to think about the supply and demand.
Case in point, college is free in Europe and that has led to the exact problem you fear: oversupply of college grads and devaluation of degrees "pushing people back into the necessary but less desirable factory/trade jobs of previous generations".
In my European college town it's easier to find a ML developer than a skilled HVAC tech or EV mechanic.
Depending on which country, but yes it definitely can be very inefficient in the nations with super generous welfare states. I know people still being students well into their late 20s or even early 30s because why not, when government pays for your education and as a student you get a lot of discounts like free public transport, cheaper phone plans, free bank plans, laptop and travel discounts, etc, so then why bother with a bad jobs market with low wages and no more discounts when you can postpone the harsh reality of adulthood?
Hot take here, but honestly IMHO, the government's constant putting their thumbs on the economic free market scale via the overly generous welfare state has been doing more harm than good to society and will lead to a rude awakening for people when the system is not solvent anymore and will have to pull the rug from under them and you have a generation of people who grew up without the skills to survive without the state holding their hand every step of the way. I expect massive political turmoil, extremism and maybe wars.
Of course you can also juice up the numbers by lowering standards so that people who don't understand numbers or basic math above a 6th grade level take on these loans without actually understanding what they are doing.
And it's worse than it looks, because this doesn't include cost of materials, the dreaded "other fees", and of course, room and board. Room and board increased 50%.
And this used to be considered a "best value" college. I'm sure it's only worse fr private schools in the state.
There is a perfect reason, though I might sympathize if you say there is no excuse. If one wanted to engineer some incredible Rube Goldberg machine to cause prices to spiral out of control beyond all lunacy, one could hardly do better than what we have in the United States right now.
Young people were told that without college/university they were doomed to a life of destitution and misery. They were hounded by teachers, guidance counselors, pundits, politicians, advice columnists, celebrities, journalists, you name it. The propaganda machine was relentless, gigantic, and hilariously un-self-aware. Then grants were minimized and replaced with student loans (unforgivable in bankruptcy, thanks Biden!).
This sets the stage. College administrators knew that everyone could now attend, and that they were guaranteed loans to pay for it, that they were young and foolish and didn't see debt as a millstone around their necks during mandatory swim time, and that they were fickle, fashion-seeking, and indifferent to lack of academic rigor. These universities needed to expand capacity to capture all those loan dollars, they were competing with other universities, and they knew their market. They built resort spa dorms... no longer were these places the dormitories of old, where you packed 6 freshman into a broom closet and made them sleep on floors. They build gorgeous grounds that looks like royal gardens. Expensive new labs and facilities and lecture halls. Why not? The kids would be paying for it (all their lives, thanks to the omnipotently powerful force of compount interest).
The kids, on the other hand, barely more than children, didn't choose the best value schools. They chose the prettiest... it's not as if they couldn't afford them. For most people, the fanciest product seems like the highest quality, and who would choose low quality? Nor could universities be the sanity limit here even if they wanted to. If they refused to build out their own little Versailles, they'd just see enrollment drop. And their costs were going up quite a bit too, when you double the size of the institution, you need more than double the staff. When the buildings are fancier than yesteryear, full of computer labs and high tech, you need more than just janitors. Entire bureaucracies were spun up just to deal with it all.
But a curious thing happened, with every university and college competing for those dollars, none really got ahead near as much as they wanted to or expected to. So they just doubled down, and tried to make their schools more attractive to prospective students. The state school in my city still strives to reach an enrollment of 50,000 last I heard (this would put it more than double its late 1980s enrollment, I think).
In summary, we have a gigantic slush fund of money that means no one has to be price-conscious, perverse incentives prodding those who administrate to jack their own expenses/costs to astronomical levels, and a society that still insists and even demands that everyone be college-bound despite the ambiguous evidence that it is good-value. Until one (or ideally all) of those things changes, there's no way for college to be any less expensive than it is.
We really are a society of ponzi schemes.
To be fair to colleges, their costs have also increased somewhat. Baumol’s Cost Disease means that it's impossible to achieve significant productivity gains in education and so labor costs continuously increase. But that only accounts for a fraction of the total increase in college tuitions and fees.
