Uh, we're from eastern Europe where everyone in the country is the same ethnicity. We had the extreme rich and the extreme poor and we all behaved. Money and civility are two different things. In fact we had communism which followed and really kept people out of opportunities. We didn't walk around acting like rednecks or gangsters. Same as in the USA 50 years ago. When blacks and whites used different bathrooms, and racial segregation was at its peak, still both black and white communities dressed well to go to church, authority was more respected, the family stayed in tact, sex before marriage was taboo. Now despite "integration and desegregation" culture and morality has rotted out society.
Long story short, I don't agree with "government is the problem, government is the solution". Low culture and standards are the problem. High culture and standards are the solution. Regardless of neighborhood or income.
