What amazes me is that for some reason you believe the USA is the only
"melting pot" on the planet.

Anyone with any ability to observe the world around them can see the USA is no
longer a melting pot. People that come to the USA these days no longer want to
"melt in" They want their own highway signs because they are too lazy to learn
the language. In some US towns close to the border Hispanics who have managed
to get into office have changed the "official" language in the local schools to
Spanish. Tell me that's "melting in"
