I read Lee Kuan Yew's book on the development of Singapore From Third World to First some time ago and recall it being startlingly rational and scarily pragmatic. (Detractors would probably say revisionist and self-congratulatory but, even if that is true, most Western leaders wouldn't even try to portray themselves as detached, rational and pragmatic.) I'm sure if there were a more rational means of statecraft (say, large-scale computer simulations) such a one-party state would be able to take greater advantage of it providing they're not compromised by some other ideology (religion or communism).
