I’m sure all the above is accurate, but I recall when I attended a private university in the early seventies, my father was appalled at the 5K/yr. tuition, room and board. In the context of those years, it was a huge amount, not “affordable” to most. I also remember that he was absolutely convinced that in a few more years, college costs would get so high that no one could afford them and the federal government would have to step in to subsidize the cost. Still waiting on that!
