I have a disdain for the advocacy of 'noble' Robin hood act. You might be taking from the rich, the rich will take it back in a smarter way. And in this process you are only robbing the poor psychologically...anyone that consider himself poor is defeated anyway.
The Communists only pay attention to equality neglecting totally the efforts put by individual or group. The fair word is equity... Give everyone a level playing ground and let each effort determine will group he belongs.
