I am American. Therefore, due to American Arrogance and American Mixing Pot techniques, I am superior and worthy of admiration

Warning: Do not stare or admire too hard- your eyes may become damaged and will deprive you of future admiration and observation of American Glory. 

No but really- go to a city and you'll find Japanese, Chinese, Hispanic, French, Italian, Indian, all of that. My dad has an Italian buddy at Texas Tech, the majority of smart professors there are Indian, Chinese, or Japanese, and the town I live in is primarily Hispanics, and you can find pretty much anything else in any state. Just search around for a bit.

EDIT: 
Think about it as stores. Every nation sells something. Then here's America, with the Wal-Mart Superstore.
