Sounds like there's a grandson who's being groomed for that: https://en.wikipedia.org/wiki/Howard_Warren_Buffett
They all seem very similar to the British "new nobility" in the mid-late 19th century, albeit with less syphilis and opium.
Is grooming the right word here? The guy is 42, grooming to me has a pedophilic connotation.
