It may be disgusting but it is pretty much impossible to stop. If you tax these individuals in a punitive manner, they'll just move the money to other countries with lower tax rates. If you try to regulate the size of the house without reference to the lot size (so that a mega-mansion can't be built even on a lot of adequate size), then the owner is just going to build it elsewhere, either in another juristiction, another state, or another country. Anyone with the resources to build a 75 millon dollar home certainly has the resources to fly to Mexico, Canada, or elsewhere if that's where he can build his dream home.
I don't work on mega-mansions like this, but a good friend of mine is an architect who does from time to time. He has made a career of working for construction companies who need professional level help in coordinating the work of the design architects, landscape architects, interior designers, etc. He recently ended two years of working extensively on a mega-mansion on the California coast, and that project helped support him and his family for that time. I'd much rather see guys like this benefit than people elsewhere if the homeowner prefers to build in California in the first place, as opposed to forcing him to take his money out of the state.
Hopefully the owner of the 75 million dollar home does contribute to charity. If not, then at least he must have employed many people while he made his fortune and that certainly does benefit the region.
