A way of life that has been tested before and found wanting

A series of passages from the recently read Black Rednecks and White Liberals by Thomas Sowell. Combative to the point of provocative but as usual crammed with unexpected facts or interpretations of facts. Page 63.

Whether black redneck values and lifestyle are a lineal descendant of white redneck values and lifestyle, as suggested here, or a social phenomenon arising independently within the black community and only coincidentally similar, it is still a way of life that has been tested before and found wanting, as shown by its erosion over the generations among whites who experienced its counterproductive consequences. By making black redneck behavior a sacrosanct part of black cultural identity, white liberals and others who excuse, celebrate or otherwise perpetuate that lifestyle not only preserve it among that fraction of the black population which has not yet escaped from it, but have contributed to its spread up the social scale to middle class black young people who feel a need to be true to their racial identity, lest they be thought to be "acting white." It is the spread of a social poison, however much either black or white intellectuals try to pretty it up or try to find some deeper meaning in it.
