> Of course, there are exceptional European universities and there are terrible American universities, but overall, American university systems seem to be much better than the equivalent in "free" university countries.

I personally think that the typical German university is better than the typical US one, but it is a very different system: In Germany you are very much on your own when you are studying. This teaches you a lot about self-discipline, which employers love. On the other hand, if you are a person who needs a lot of handholding, German universities are probably not for you. In my opinion being able to study mostly for free is more than worth the lack of handholding, but as I said: This system is not for everybody.
