The failure of Contemporary Suburbia has nothing to do with being un-American. It has failed for three reasons:
1) Almost of the "Contemporary Suburban" developments are characterized by very high-end units in very suburban and exurban areas. People who can afford to pay very high prices for housing tend to be very social. It's all about sipping coffee and chatting with your neighbor across the way or participating in the vibrant community life of a real downtown. They don't want to be dependent on their car for everything. It simply has to be urban!
2) People with money are looking for uniques housing, not the bland vinyl "HcHomes" that dominate the suburban landscape of the last forty years, and
3) It was a dumb idea to begin with, an attempt to make a city seem like the rural countryside.
Thanks god it's dead! Our local suburban proponent is an over-paid lawyer who lives in a big historic house in the city center... Get Real!
