Communism is a system of government that considers all property community owned. In this system the government collects everything and then the community is provided for and given what is needed. There is no incentive to excel because everyone is treated equally, regardless of their efforts, their level of success, or their contributions to the community. Those who are lazy and do nothing benefit just as much as those who work hard many hours each day.
