China is slowly changing from a command market too. United States - Mainly a Market Economy Most of the businesses in USA are privately owned.
Entrepreneurs borrow money from banks or get money from investors by selling stocks and shares.
They use the money to create and run a business which brings in profits. The profits are used to pay off debts and repay those who invested time and money in the firm. The success of a company depends on its ability to sell its goods and services to others. If the market is good, profits will be high. If few people buy the products of services, the company may collapse.
