Granted, you could just earn more than $100k a year, and consequently price yourself above much of the riff-raff.....But, lets say you're a run-of-the-mill blue collar union worker, and raising your family in a low crime, graffiti-free neighborhood is of the utmost importance to you... If there were developments that were priced in your target zone that offered "Immigrant free", or "Caucasian & Asian only" neighborhoods..would you buy there even though it wasn't necessarily socially sensitive ?.... Would the desire to raise your family in a safe neighborhood (where schools were at the top of quality-curve, etc etc) supersede the need to exhibit racial equality? Would you hesitate to tell you friends, family & co-workers where you've decided to live??
