Communism

Communism is a great idea, and a lot of people likes the sound of it.  But most people forgot the nature of human laziness brought down nearly all the communist regime.  The greed of human, namely power and influences, corrupted the noble idea that all citizen contribute to the countries.  We forgot how without incentive, human will power alone cannot carry a nation of lazy people.  Then countries GDP were non-existence, and basic supplies were scarce.  So when people with little historic understanding of the communist ideas and communist nations said, "communist is a good idea."  One can only shake their head than think, "how naive."
