I'm not talking about individual cases. As a whole the bottom 20% lack upward mobility. How can an entire class of the population be lazy where other classes aren't? Is it genetic? Is there a laziness gene that causes them to be failures, which they pass on to their children? How does it manage to afflict all the races, but solely be dependent on income?
I got that you felt it was laziness in your previous post. I would just like you to explain how a socioeconomic group can exhibit specific personality traits that others don't seem to. How is it possible that people who are born into worse situations also happen to have a predisposition to laziness? How does laziness know to afflict people in certain classes and not others?
Because the poor choices that their parents make are handed down to teach the children these same poor choices and it repeats. That and being successful gets you labeled an uncle tom by your peers and family.
