I read lots of Miller, and also some of the Psychohistory stuff (Basically the history of child raising and its influence on the society of the next generation)

It is however important to notice that both are highly controversial, and maybe simplify complicated issues.

In case you want to raise a dictator it is not enough to severely abuse the kid and let it grow in absolute despair. I would expect there is something else that plays a role. And I am curious to know what it is.
