What are you getting at? If you're talking about Brezhnev, I don't think he was crazy when he was in power. His inner circle did everything for him, and they did the same thing as now – they grabbed as much as they could. Only now they grab strictly according to the hierarchy, with the President at the head, and back then it was chaotic and without Brezhnev himself.
"The king is made by his retinue" – this has always been the case and probably will be, we just don't know anything...
