Capitalism

What Does Capitalism Mean?
An economic system based on a free market, open competition, profit motive and private ownership of the means of production. Capitalism encourages private investment and business, compared to a government-controlled economy. Investors in these private companies (i.e. shareholders) also own the firms and are known as capitalists. 

Investopedia explains Capitalism
In such a system, individuals and firms have the right to own and use wealth to earn income and to sell and purchase labor for wages with little or no government control. The function of regulating the economy is then achieved mainly through the operation of market forces where prices and profit dictate where and how resources are used and allocated. The U.S. is a capitalistic system.
