Communism collapsed upon itself when a better form of government/society aroused.

Well, um... yeah. That did kind of happen. Now, your idea of "better" my be different than mine, but I like to think that people circumventing a giant wall for two hundred miles to escape a form of government for a different one might hint as to thier preference of one over another. And, as in the case of Good ol' Gorby, we can see that once Democratization, Glasnost, and Perestroika were introduced, the people, again, showed their preference, causing the largest communist nation, the USSR, to collapse. Which undoubtedly ed to almost every other communist nation in the world to collapse also (with the exception of China, whose Maoist Communism is quite different indeed).

So yes, I would say that communism collapsed once capitalism, a form of government seen as "better" by the communist people, aroused.

Communism was doomed from the very beginning. I was an illness of mankind. It's my point.

Well, the big word in your claim is the word "when". I do not doubt that communism was doomed from the get-go. But it did work for a few decades, so saying that it occured "when" a better form of government was aroused is certainly accurate. The two events occured almost simultaneously.

I see. Sorry. I should say: attempts of building communism were doomed from the very beginning.

We mix to different thing: communism as ideology and philosophy (say, abstract project) and communism as phenomena: Soviet, Maoist, North Korean, Kampuchean - attempts to realise this abstract project.

Capitalism existed before communism ever did, so the appearance of capitalism didn't kill communism. Communism collapsed when the communists could no longer maintain the illusion of success.
