I think that tearing down the public housing projects and switching to direct payments to landlords (Section 8) has been shown to have shifted some poverty from inner cities to the suburbs. That was a main reason for Section 8, so I guess it has been a success. I can see that moving poverty to the suburbs will hit some rough spots, but in the long run its good policy. However, nothing great will happen until we as a society decide to eliminate most poverty, as several nations have already done.
