What is the pro and con living in Europe?

A lot of people move back to Europe. I have been there for travel. I like people there. I think Americans are more discriminating and secretive. I was wondering what other people think? Would you move to EU if you have a chance? I am east Asian by the way.

I have no plan to move there. I lived there for year and a half and I didn’t like it because Europeans have American dreams. I came back but I really like the quietness. People are logical.
