Amid all the assessments of the candidates in last Tuesday’s Democratic debate, relatively little was said about the substance of their proposals. One item that stood out was college tuition — a subject that should remind voters of the old adage, there’s no such thing as a free lunch.

Democrats like to frame their proposals as one for “free college tuition,” but there is no such thing. Teachers and administrators cannot afford to work for free. Someone has to pay them. If you work for a living, that someone just happens to be you. Having already paid for your own college education, you now have the privilege of doing it all over again for someone else.
