Ah, sorry, when I said "the question why the larger US (or English-speaking) culture isn't uniformly doing the same" I meant "why there isn't greater pushback" not "why aren't there other MrBeasts" (although that was my assumption).
It's very interesting that the phenomenon itself is multi-cultural, though. Or maybe it's internet-cultural? It's probably tied into the nature of human beings and people exploiting that.
