People from Europe are going to other countries for employment, not all but some such as Spain,Portugal,Italy .Why would you think of going to Europe?Education might be free , but learning new language and getting jobs wont be easy as in the US. United states is a diverse country with so many people from all over the world, and still there is some racism and discrimination specially, if you go to ;ess  populated states with majority white populations such as North Dakotas,South Dakotas,Iowa, Idaho etcs...But atleast, you have more rights here in the US. Europe except England, may not be that diverse.Personally,I wouldnt imagine living in Europe even though they have very high living standards, but those are for native Europeans.
