European Union is basically many countries living together as one too. I can move between countries without any problem. I can work in any other EU country just as easily as I can in my home country. How about you consider Sweden as one province of EU. Are you really saying that different cultures aren't getting along here? What you win at economy you lose in quality of life.

If we are entirely honest, you don't have anywhere near the level of social mobility across the EU as across the U.S.A.

So what can't I do when I go to other EU country that you can when changing state in US? I still get health care, I still can work there, I can move there if i so desire. What can't I do what I could possibly still want?

You are a foreigner when you move to a different place across EU, with all social implications. A worker moving from LA to NYC is not nearly as disadvantaged as one moving from say Sicily to Sweden.

Of course you are able to move freely and there's no legal barrier preventing your employment, but in practice you are rarely on equal footing with locals. There are both linguistic and cultural externalities at work here, which are simply absent over the pond.
