Jealousy and envy?

Help them clean up their own areas.

Putting them in 'nicer' neighborhoods will not create utopias. It has been tried and it failed. That is part of the reason why suburbs were created -- people willing to move away, rather than be subjected to increases crime and violence.

Population density makes a difference. Higher density leads to more interactions and more potential friction. For me < 50 peeps/ mi^2 is about the limit.
