Community colleges print the right kind of paper in some circumstances (e.g. paramedic certification, different medical technicians, firefighting), and if tuition is free, they can reduce student loan burden. So IMO, free tuition is a great idea (maybe they'll extend it to the public four colleges, as California used to do back when we were serious about investing in the next generation).

But the real problem is too few jobs for semi-skilled people for whom college isn't a realistic option. The idea that we can fix that by making community college free or by sending more people to college in high school is ludicrous. They still won't do well.
