These people can't get jobs. They're unemployable.
British historian Max Hastings put it best in his recent brilliant article:

So there we have it: a large, amoral, brutalised sub-culture of young British people who lack education because they have no will to learn, and skills which might make them employable. They are too idle to accept work waitressing or doing domestic labour, which is why almost all such jobs are filled by immigrants.
They have no code of values to dissuade them from behaving anti-socially or, indeed, criminally, and small chance of being punished if they do so. They have no sense of responsibility for themselves, far less towards others, and look to no future beyond the next meal, sexual encounter or TV football game.
They are an absolute deadweight upon society, because they contribute nothing yet cost the taxpayer billions..."
Long article but well worth the read. Applies to the American underclass just as equally.
