The notion of amoral familism was proposed by Bansfield in the early 1960s and reproposed by Fukuyama in his book on Trust.
Amoral familism was seen as something that Catholic Italy and China had in common. Possibly true.
Amoral familism seems to be rampant in Africa as well. The children of former presidents, become presidents, the children of former presidents become CEO of important state-owned enterprises, and the wives of sitting Presidents become or are expected to become vice-presidents.
