Yes, and this is related to the reasons the concept of the nouveaux riches and their crass flaunting is very old. People with multi-generational wealth figured out a long time ago that flaunting wealth may feel good for minutes, but it brings the wrong kind of attention for decades, and that wrong kind of attention can be the guillotine.
