Have you even traveled much across this huge and deeply diverse country? Or do you just stereotype and generalize by pulling assumptions out of thin air?
There are also many, many very clean communities in the United States, and many people or groups of people who despite loving their personal freedoms and individualism, also take community spirit very seriously in many ways. The country has been famous for this for centuries.
Goddam how simplistic some of the U.S bashing on this site can be, much of it based on incredible levels of ignorance and caricaturesque notions from people who don't even live in the country. Many of them Europeans too, who should know a bit better about avoiding stupid stereotypes and simplistic depictions of complex cultures.
