> No, it's because no matter what the cost of school is, universities know their "customers" will just take out a loan to match whatever the price is. And one way to "disrupt" this is to make public universities free for in state students
It's not just the ability to borrow that's driving this, but the perception that you must absolutely have the product (college degree) - so you don't feel like you have a choice not to borrow to pay the exorbitant fee.
University is hard to "disrupt" but the fact that the cost comes out of your pocket, student debt and all, is one motivating factor for others to try.
If you entrench the university as something that's "free" (meaning, you still pay the exorbitant fee, just in the form of taxes) then you've basically established a monopoly because nothing can compete with something that's "free"
My take on the university is simple - the university originally existed because you needed a single physical location for books and smart people. Access to people and information was finite and location really mattered.
This is the opposite of the world we live in now - ability to access people and knowledge today is only hurt by the physical colocation aspect. So the university, which is still operating under the "books and smart people are scarce so you need to pay us to be near them" principle just no longer makes sense as the default way to educate the masses.
