More importantly, nobody is going to commit to 30 years of mortgage payments (and risk losing value anyway) if the government can just turn their neighborhood into Harlem on a whim. Since many whites no longer breed, they are no longer in the market for homes anyway; this battle will increasingly be fought between blacks awaiting transport to an area where taxayers can provide them with housing, public schools, and emergency services and the Asians who are moving into the formerly white areas.
That is why I now live in an unincorporated part of a rural county. The drive to work is a major haul. My neighbors are nice. Unless asked, we all just leave each other alone. Not everyone can or wants to leave the cities. Those that want to leave, however, are doing so in droves. What used to be open farmland is now sprouting new homes. Many of these new developments also have minimum square footage requirements, effectively pricing undesirables out of the area.
When given the choice, I would much rather have an Asian family living next door than a nest of urban ferals.
