And there I am, with my double degrees from a German Unibersity and not a single Euro in student debt... Instead of the average of student debt in the US, we have a mortgage on hous, and a house obviously. All that despite paying taxes, which also cover stuff like higher education.

Because do not forget, you pay taxes in the US as well. On top of your student loans and whatnot.

And no, Germany tried to cut tuition fees already. Those were abolished after, if memory serves well, a year or two.
