Most property, for example, is owned by people or companies, not by the government or by the workers. Capitalism has a more or less free market economy, which means that prices move up or down according to the availability of the products. People buy and sell things according to their own judgment. In most countries there is some regulation (trade laws) and some planning done by the government. They are sometimes called "mixed economies" to indicate this. Some people disagree on whether capitalism is a good idea, or how much of capitalism is a good idea.
