By your definition I am Republican - upper class.
However, I live in a very expensive area, and I consider my income to be upper middle class for where I live. In Arkansas, I would be upper class, but here I'm simply upper middle class. I'm comfortable; I don't have to budget myself too carefully, but I can't afford to stop working for any length of time.
I'm sure where you live is cheap to live compared to SF.
Not really. I know SF is very expensive, but so is Fairfield County, CT.
It seems that coastal areas with natural boundaries tend to be the most expensive, because expansion is limited. Housing in Texas is cheap, because land is flat and plentiful. In the New York area, there are bodies of water that limit the availability of land within a reasonable distance of the city. Same thing in California, especially San Francisco, with the bay and and mountains.
California real estate from what I heard has gone way out of whack in terms of price. I find it a scary trend. I hate the extreme economic segmentation that these prices bring. One of the reasons I picked my town 10 years ago was the economic diversity - it had housing for every economic class except the poor. Now, over time, the lower classes are being pushed out, as the smaller houses are expanded into big houses, and housing becomes ever more expensive.
