Is America too rich?

I have been doing Real Estate Appraising lately. I have the chance to witness new housing developments that are popping up around Orange County and the surrounding areas. The development I am most interested in for today is Ladera Ranch. These houses are nice. They are like manor houses, but instead of one manor per royalty, there are 50 on each block. I'm stunned. Where do we get all this money? The money exchanging hands in Ladera ranch involves builders, designers, and home-owners, all of whom are making or spending enough cash (an average-sized 2000 sq. ft. house goes for 800,000) to fund the resurrection of third-world governments. Is it acceptable to spend so much money on our living arrangements? I do not think that there is ever excess of beauty or excellent craftsmanship; the question is of priority. Some of these men and women in Orange County have enough money to casually toss it around wherever they please. Is there not something on which they could spend it in earnest first?
