It costs someone something, but no one their freedom. Mass ignorance is the opposite. As for degrees with no use, pretty sure these are the byproducts of education for profit, with heavy marketing passing as administrative expense. Maybe you could divide the system in two halves: 1) Of national interest, 2) Discretionary. As for earning potential, it has nothing to do with free education, as so many high-earners in the US were educated by such systems.
