I've been there a couple of times.
It's interesting to think of the social structures that allowed the accumulation of that kind of wealth.
If I'm not mistaken, when G. V. built the place, there was no income tax, no IRS, no real restrictions on the amount of art, materials, etc., that
could be imported without some kind of tariff or tax.
There were no unions for construction, plumbing, electricians, etc. I'm not sure there was even property tax.
My thought is that there is an active cadre of people who wish to live like that again, while disallowing that kind of life for us down here in the
unwashed mass class. Vassal / serf type stuff. One set of rules and barriers for us, and none for them.
