There is an argument to be made that the nature of Anglo American society in the 1950's was a result of DNA plus a Constitution that fit the nature of the people. For my grandparents (owned property in Newark NJ) but when it was clear that certain elements were moving in they gave away their property. They did not sell, but gave away since they realized that even owning property in such an area was a liability.  In a similar way I recall Camden NJ where the sister of my mother used to live. And we visited there every summer. It was wholesome and clean. Now it has become an extremely  violent city. Same reason.

The moral is clear. The South was right.
