> Though it won’t be a small class of rich, it will be a couple of overpowerful families only. I don’t think we have any examples to compare too.

A couple of powerful families? Where power is transmitted from generation to generation?

I can't think of any examples either, it's a very novel concept.

Oh, wait. Romanovs. Merovingians. Carolingians. Capetiens. Bourbons. Habsburgs. Hohenzollerns. Tudors.

Extremely novel concept :-)
