Of course it’s not free. And why are so few of the best universities European?

Your orig post says subsidizing makes college more expensive, now you are saying they are not best. Why switching the topic of your argument?

It makes it more expensive at constant quality, and worse at constant cost. Got it?

Am not agreeing at all that, at constant quality, US univ are cheaper. What numbers are you basing your claims on?

That's not what I said.

so if at constant quality US univ are more expensive than EU ones, what do you think makes the US system less efficient?

Not constant: US universities are both better and more expensive than European ones.

Doctoral programs in the top 50 universities in the US are good. But good undergraduate and Master-level STEM education in much of Europe is better than in almost all US universities. And they largely public and free, or private and almost free (by US standards).
