I don’t know if that’s actually true.  Are you sure?  Can you provide some evidence?  We could go find some data!

I’m not sure that I can give a complete answer to that, but I’d say part of the answer is that because of slavery, there are historic factors at work.  Many people are raised to not really understand how to be independent and productive members of society.  There are a lot of historical, institutional, and economic factors that perpetuate inequality.  But people can definitely learn to overcome these problems and there are specific policies that can help.
