what is communism

Communism is where each piece of land is publicly owned and where each person works and is payed according to their needs. This is a major problem because one guy could work hard and really earn his wealth. Then there is another guy that is poor and does  not work so much. This is a problem because then under the communism law, they have to pay this man for not working hard because he is needy for money. This would be unfair to the hard working man because he has money and is not needy and worked for his money but is not getting money from the government because he is not poor.
