You think you've seen rich?
Walk into The Breakers and check out how they had platinum, instead of silver, in some of the mansion's "ornamentation", because silver rusts. So, no biggie, we'll just buy platinum top get that shiny silvery look!
The Vanderbilts also had the pleasure of making their money well before the government decided to start taxing earnings.
Also, don't you dare take any pictures up in that piece - there are goons all over the place that will kick you out.
