First used by Israel Zangwill in a 1908 play‚ the term “Melting Pot” considers the American Dream‚ the incorporation and Americanization of immigrants in the American society.

America today is thought to be the melting pot of the free‚ where people from far and wide can come to enjoy a life of ease. As what Jimmy Carter says “We become not a melting pot but a beautiful mosaic. Different people‚ different beliefs‚ different yearnings‚ different hopes‚ different dream”.

It is set at a train station in between Barcelona and Madrid
