First, there’s a big difference between cities in both places. I could believe that if you compare California to Bratislav, but Oklahoma to Vienna would already be a different matter.
And in any case, it depends how much worse it was. In the US, even if it’s “state funded”, you have to pay for it, and quite a lot. Chances are if you went to a private clinic in Central Europe paying that same amount of money you could’ve gotten the same, if not better treatment.
