"socialists" and "communists" are people who do not support capitalism. they say it hurts workers, because businesses make more money by selling things than they pay the workers who make the things. business owners become rich while workers remain poor and exploited (taken advantage of). they also argue society would be more efficient if people thought less about competing against one another for their own interests and thought more of working together for the overall good of society. another argument is that each person has a right to basic needs (such as food and shelter). within capitalism, sometimes people might not get everything they need to live. capitalism is also said to be the main culprit of economic inequality.
