You are from Europe, right? And you have rigorious exams to sort out the folks who will get the government-paid education and who will not. And this is ok, since Europe is more or less homogenous. Hans goes to university and Peter and Mark and Bernard all go to work in mcdonalds instead. No outrage here, it was just a hard exam, and only Hans was able to pass.
Now guess what will happen in US if you don't provide free education for everyone, but require to pass a hard exam first. It's not that hard to imagine, really.
