ELI5: Why is the US college tuition so high?

And where is the money going? Are all colleges private?

Price discrimination. Those who can afford to pay, do so. Those who can't are given various amounts of financial aid to lower the price to a more reasonable amount.

At least it works like that ideally. In actuality many people have to take out loans, although by going to state schools you can limit those loans to well under $50k. But making all college free would just help the rich more than anyone else, since they pay by far the most college tuition.
