Your European parents paid that $30K and more in additional taxes though. The money came from somewhere; land and buildings and qualified professors do not come for free in Europe.
Well, sure, but it isn't like taxes are that much higher - honestly, my taxes moving from the US to Norway weren't realistically higher than state + federal + health insurance, and if you consider the out of pocket for health care, the bill is cheaper. Not to mention that Folks that go to school and wind up working a lower-paying job (teaching, for example) aren't on the hook for all of it either.
And you aren't even paying for the same sort of things: Many colleges have sports teams in the US, for example, and the degrees take longer in the US. For example, you don't have to get an undergraduate degree in Norway to become a doctor so you spend less time actually in school.
I'm failing to connect your comment with mine. Yes, of course it came from additional taxes. Those additional taxes did not put people into $30K of debt in those countries. If you're poor, you don't pay that much in taxes. My mythical European parents did not get go into debt paying those taxes so I could go to school.
Another commenter pointed out that German universities need 1.3% of GDP to educate 27% of the population without charging them tuition. USA actually gives more public funding to colleges than Germany and yet those colleges are still asking for tuition.
