What good would it have done for OP to list the names of "families that nobody talks about"? Listing Bezos/Musk is an easy way to just say, "richest mother fuckers in the world". You don't have the same impact if you list a name that nobody knows.

Because then it would be, "The US government works for the Clarks of the world," and we'd all be going, "Huh?".
