Absolutely insane and immoral. Not only are some of these "developments" very tacky, the majority of owners don't plan to live in them year round. Some sit high on ridges so they are visible for 20 miles, cluttering up the landscape for everyone to see.
I am all for the Horatio Alger story repeated 1,000,000 times in America, but I just wish the noveaux rich would learn a little class and respect for their neighbors.
I tend to agree with you assessment, but my point was that somebody is making enough money to build these houses, and many as you say only live there part time which means they have another equally ostentatious house somewhere else.
