It appears you didn't read my reply, Torie.
You suggested that there are tons of native born Americans not doing much, who are not counted in the unemmployment statistics. I suggested otherwise. Sure there is internal movement, with low and semi skilled African Americans tending to remove themselves in particular from places where they are high numbers of Latinos. That is part of the dynamic economy to which I am referring. I regret that you think I missed your point. Perhaps I have.
