That's exactly what's going on in Arizona. HUD relocation programs are moving people from the ghettos as far away as Cleveland and Detroit to vacant/foreclosed home in the metro Phoenix area. This has been going on at a very rapid pace over the last couple of years.
That is exactly what California Welfare does. Why live in the cities where the cost of living is higher, when you can move to the Rural areas and live where people go to retire. Now in the ski resorts areas, California has crack head slums being supported by the dole. Then they closed logging and mining and farming off. Instant collapse of the rural areas. Once higher than average employment, now 40% unemployed. You want to work for a living move to the city, you want to retire on drugs, get welfare and move to the country.
