One, I don’t believe it has to be that way. With enough taxes on the wealthy, regulation on commerce, and social programs for the poor, I think a system of fairness can be achieved.
Two, I don’t believe that communism of any form result in a sense of fairness for anyone. I believe most humans have an innate desire to work to improve their lives, and I don’t believe communism offers the same freedom and opportunities for self improvement through honest work that can be offered by tightly regulated capitalism in combination with strong social programs.
