One of my father’s cousins won the San Fransisco lottery, years back. She bought a massive house for the family, overlooking San Francisco Bay, and cruised back to Europe every summer, inviting all her relatives to a big dinner in a hotel each year, which was how I met her.
It was good meeting relatives I would otherwise not have encountered.
My impression from those hotel meetings was that her kids grew up entitled, though, thinking that everything should be theirs for the asking - somewhere during their childhood they seemed to lose their drive for self determination…great result for the parents but perhaps not so much for the kids…? I don’t know how it panned out in the longer term.
