What is Communism/Why or why not socialism

Why socialism Why not socialism Indeed, why not be satisfied with a society where everyone have basic needs generously provided with minimum exertion of personal labour? This question assumes that humans are essentially creative and when socially necessary labour demands little of their free time they strive towards self actualisation. Given the above, then assumption is that form this grass roots freedom-condition a maximally free society will emerge. Spelling out in detail what the various institutions and their interactions will be is a design step too far.
