There is, but it’s basically made up to support the notion that it’s very difficult to stay rich. It’s actually very rare for subsequent generations to lose inherited wealth, it just gets partitioned out so there are dozens or hundreds of rich people instead of one disgustingly wealthy individual.

What? It’s literally the opposite. Do you remember the discovery that owning horses extends your lifespan by several years, not for any merit of its own, but because it strictly excludes the poor and most of the middle class?
