Communists agree with the free enterprise system.
true
false

False. Communism is an internally stable economic system, in that those that participate benefit and those that don't are culled - creating an incentive to participate. 

Communism requires common goals and agreed upon rules/laws to allocate responsibilities and resources. If successful, this leads to a spirit of sharing - which builds stronger social communities, creating a stabler economy. 

Due to their sense of cooperation, healthy communistic systems are very efficient at distributing resources within their localized areas - particularly in times of need.
