Karl Marx and Communism

Karl Marx did not like factory owners and landlords controlling workers beacuse thee used the workers and working conditions were terrible. So he thought of this idea of communism, so that nobody owned a house, land, factory or a business. Everything was owned by the government, and everybody made the same amount of money. The good thing about this was that nobody was poor but the bad thing is that everybody made the same amount of money with a job. This did not work out because people said why should i be a doctor to be rich when i could be a regular grocery store empolyee. Communism fell after 70 years in Russia.
