The biggest mistake of communism is that it assumes that entrepreneurship is economically worthless. It's literally the opposite extreme of capitalism which assumes that entrepreneurship is the most important profession.
I think communism might have worked better if it had given more autonomy to managers to make decisions and used output data for the previous year to decide budgets for each factory/company.
Really sucks that the word communism is now used to describe Lenin's legacy. Even the USSR 'communists' said that what they have is not communism.. but 'socialism'.
Prior to the rise of the Bolsheviks, there were a number of Marxists that were equally popular as Lenin such as Rosa Luxemburg. They were opposed to what the Bolsheviks were preaching.
Nowadays, now a listener of Prof. Richard Wolff and his the Democracy at Work project he started.
