What Form of Elitism

Which spending habits of the 1% are deemed acceptable behavior?

Billionaires frequently show up to work dressed in jeans and T-shirts (black preferred). Typically live in small towns, drive 10 year old cars, and eat in diners. While it's acceptable for someone making $200,000+ a year to spend money on any room in the house formerly used by servants. But vulgar to spend on adult toys such as fast cars for the pleasure it might bring.
