The Bell Imperative

 Clark published a new research paper concluding that "aspirations that by appropriate social design, rates of social mobility can be substantially increased will prove futile. We have to be resigned to living in a world where social outcomes are substantially determined at birth."

Clark studied the genetic changes in the English population on the basis of surnames. In a few hundred years the surnames of lower/criminal class have disappeared, replaced by descendants of the upper/richer classes. In our generation, it seems to work on the reverse. 

Why this happened in South East England and not in Bulgaria? England was/is a stable, well-governed society for centuries, where violence does not pay. Bulgaria was a frontier lawless region, where violence and brutality was survival necessity.
