Actually, education should not be free, not even K-12. Everyone should pay something, or education is seen as free and therefore of little value. It should not be out of reach of anyone, however, and it should be possible to graduate debt free. We don't want to make schooling difficult to obtain if we want to have an educated population.
We do want to have an educated population, don't we? The alternative is to become like a third world country.
Can't we just turn Congress off and then turn it back on again?
