The people saying the US has huge cultural diversity are killing me. The US has terrible cultural diversity for a country of its size. The fact that everyone speaks the same language with little differences between dialects should clue you in on the relative lack of cultural diversity. Mexico has more cultural diversity within it despite being a quarter of the US's size. An actual culturally diverse country would be something like Nigeria, which is culturally three different countries stapled together with hundreds of ethnic groups with their own unique culture and their own language within each of those three subcountries. Nigeria is also a tenth the size of the US.
