On the other hand, TUM (technical university in Munich) costs only 220 euro per semester, and you're still enrolled into top25 university in the world.
The land of free..
We can debate about whether that's a good use of money, or what spending priorities should be. Maybe the right thing to do is cut costs, preserving an equivalent education experience while cutting frills. Or, maybe Americans are so rich it's reasonable for us to splurge on all of that stuff. But Americans aren't irrational. It's not like Americans are just sitting here refusing to adopt an approach that would get them the same college experience for vastly less money.
It's not. I can get a gym membership for $10/month. And I'm not going to college to get a degree in physical fitness.
And, your argument doesn't hold numerically. Say 440 euros/year = $500/year. That's 1/200 the cost to the student of the University of Chicago. So Chicago spends 5 times as much per student; it still looks insane from the cost/benefit perspective.
