College made sense for a very long time because a lot of books were hard to come by for regular folk, and the cost was reasonable.
They were great places for young adults to complete the transition to “adult”, to experiment and figure how who they want to be.
These days the costs seem to far outstrip the benefits, and the Internet makes so much more accessible at a young age.
Parents and kids are finding it hard to justify hundreds of thousands of dollars just to “figure things out”, as we used to.
