On the other hand, nobody wants public housing projects being set up in their nice neighborhoods...often for good reason. The once-safe neighborhood where I grew up once had a grocery store - the lot was bought out by neighborhood housing, a low-income development was planned, locals complained, locals were called racists and NIMBYs, development was built anyway - and now there's no grocery store, no parking, shootings and burglaries are regular occurrences, and kids don't play outside.

The problem isn't solved by spreading poverty and dysfunction around rather than concentrating it - it just makes it everyone's (read: your) problem.
