Firstly, NO, the US is a country, the EU is not.

Secondly, even if the US as a country is tighter integrated and more financially successful than the EU as a union, the US is not a successful model example of a well functioning society that people in the EU would aspire to emulate, on the contrary, they'd rather preserve the status quo than turning into something resembling what the US has become.

Right. That's exactly what I'm claiming, that the EU has to become more like a confederation, more closely integrated than it is now but less integrated than modern federations like the USA or Germany. Closer to the early USA (where the states had more power compared to today and the federal government less).

It has zero to do with communism.

>Isn’t this exactly how the United States and every other country works?

EU is not a country. It's a political and economic union. And I think it can't become a country since peoples of member states desire to keep a degree of national sovereignty.
