>Yes, this is exactly why college is so expensive right now. Guaranteed federal loans without any default option was supposed to make the barrier to entry easier, but instead just added a zero onto the cost.

College has became more expensive because it's a cartel of trophy diplomas.

Unlike housing, the physical limitation of a classroom size should practically not exist anymore.

With the multiplicative benefits of technology, the same lecturer could be teaching a class of thousands of students.

But instead of costs going down, it has actually went up.

Classes that require physical presence (such as labs) can scale a lot too. They mostly sit empty, whereas they could have lab sessions every waking hour of the week, with of gains of scale reducing the costs of education.

The rising costs of textbooks is another blatant broken market problem. Printing textbooks should be as cheap as ever now.
