What is the role of the communist party?

Communism, as the name suggests, provides a communal pot of goods and services that everyone on the country has access to, despite social status.

The Government's job, hypothetically, is to make sure all of the goods and resources are distributed evenly and that everyone who has put into the pot, has access to the goods.

Communist governments make sure that factory workers get their pensions farmers meet their quotas and that food is readily available wherever it may be needed.

Communist leaders can either be appointed or elected, but their goal is to make sure that all members of society are reciting their goods and moneys fairly despite social stature. However, giving the government that much power has often led to the system breaking down for corrupt officials, and although not always, communist governments are often times absolute and ruthless when people start to fight them. Many communist governments view a protest as "mutiny or treason"
