Its a shame since I would expect them to have better sense than that to have accumulated that much wealth. Then again, its their money so ¯\_(ツ)_/¯

Especially when the wealth is inherited or kleptocratic.

But if we think of wealth more than an abstract thing and more as a societal contract, then things do change a little bit. Wealth is society's way of abstracting the capacity to work. You can keep all your wealth in gold coins in a big building but without a society that values it, its really not worth that much. Wealth is a claim on other people's work, other people being members of a society. So, we have the situation that only the combination of wealth and society is actually worth anything.

If that is the case, it is in the interest of the wealthy, to foster a society in which 1) More work can be obtained in total and 2) More work can be obtained for less money. The former leads to philanthropy (betterment of society), and the latter leads to lobbying against taxation for the rich and other measures to redistribute income; since when more wealth is held by few, the few can make the many work for less (more labor than capital).

But wait, there is another dimension: if you think about the wealthy in Germany buying an expensive BMW, it still doesn't seem as bad, since the wealth is still within German society. But when you have wealthy Chinese buying a German car, then the wealth which was accumulated by the labor of the Chinese society is now going to the German society.

there is certainly some tipping point for this and after it's not worth it, and poorly-handling muscle cars leave me uninterested, but it works, it can be joy on normal roads and on track even pure adrenalin.
