Yup! The best country, the United States of America!

Neither does communism, but it exists.

Freedom of markets! The markets set the prices, and the prices are controlled by supply and demand as opposed to the government controlling how much is produced, what prices goods and services should be set at, how much people can buy, that sort of thing. The government only puts taxes on foreign imports to encourage people to buy domestic products. Private companies can import and export what they need. Under a communist regime, the government carefully controls these things to suit themselves. Then they go oppress their people, get drunk, and fail at life.
