Something along the lines of: A socioeconomic order centered around common ownership of the means of production, distribution, and exchange that allocates products to everyone in the society based on need.

I guess the point of the poster above is that the word communism just confuses things in the initial statement — it’s just a dictatorship. Socialists and communists fairly uniquely believe in workplace democracy.

A rule of thumb that makes sense to me is that communism generally differs from socialism in that it advocates one or more of the following:

- People actually living and working in communes.

- Abolition of private property (note: this is not the same as personal property).

- Extreme redistribution and/or equality in wealth/income.

I'm sure that this isn't a perfect heuristic; however, I think it's often useful for detecting when someone is trying to describe something as communism in order to make it look bad.
