I assume you're talking about college because grade school up through high school is "free" unless you go to a private school and pay tuition. The thing is, if colleges and universities were "free" and paid THE SAME by the government with taxpayer money, what incentive would any college to be say, "ivy league" status. All the colleges would be equally mediocre, pay all their professors the same money, teach all subjects in the same mediocre way, and graduate mediocre students who would go out into the world and get mediocre jobs. There would be little innovation, new ideas, or creativity. You may pay through the nose for it, but a good education gets you exposed to professors who challenge you, make you think analytically, and outside the box. There would be no Bill Gates, Steve Jobs, Zuckerbergs, Hawkings, Einsteins. Their ideas would be crushed by a mediocre education system paid for by government bureaucrats, who would be sending their kids to private schools paid for taxpayers. Hey, isn't that what they do in Communist countries!? YES IT IS!!
