Why didn't communism take off?

Communism is a political and socioeconomic ideology that defines an egalitarian society through the abolition of private property, social classes, and the state itself. Although an idea of specific use at the end of class has been altered by philosophies since ancient times, communism is associated primarily with the theory of thinkers Friedrich Engels and Karl Marx.

Communism is an excellent theory, but when brought into practice it is not viable. To this day, all practical experiences of establishing a communist regime have failed.  It preaches the end of man's exploitation of man, which puts workers in power, that democratizes the means of production, that determines that production must be geared to the interests of the population rather than the owners of the means of production.

And that is precisely what prevents it from working, is society's elite really willing to lose its power?
