Pure Capitalism. It is the only economy that is proven to work. History has showed that Communism and Socialism does not work, i.e. Soviet Union, Nazi Germany and so forth. Capitalism gives the power to the people in the economy. They decide if they want to spend their money and what they want to spend the money on. The people Choose items that they need of want, they don't need the Government telling them they need a certain item that they have to spend money on. A mixed economy has ideas of Socialism and Communism, and those ideas ruin the Capitalistic economy.
