>name a single capitalist totalitarian dictator?

Pinochet.

>Now name how many successful western countries haven't embraced capitalism as, at the very least, their main source of funds to experiment with.

Almost all western countries are capitalist I believe? Usually I take western to mean (1) democratic (2) capitalist. Besides as I'm arguing elsewhere, the failure of many socialist states is due to US intervention. Cuba's Embargo is a great example, the coup that placed Pinochet in power is another. America hates socialism/communism so it constantly acts aggressively towards those states while helping capitalist states. It's tough to look at the scoreboard and judge when the ref is obviously biased.
