Dispersing the ghettos we naively created under the guise of welfare would be ideal. Why did we think it was a good idea to round up those most affected by poverty and cram them inside dense communities where all anyone wants is to get out?
Targeting the poorest areas with subsidized low skill jobs that have gone overseas would go a long way. We think the cost of teenage pregnancies, welfare, subsidized housing, theft and vandalism, incarceration, increasing police forces, drug rehabilitation programs, & expanding local judicial branches is cheaper though.
