The free enterprise system in the United States developed soon  after the country gained its independence. This is a system that  allows people or entities to establish theiâ¦r own company, taking a  competitive stance with other businesses, and operate it for their  own profit.
A free enterprise system is an economic system where a government places very few restrictions on the types of business activities or ownership in which citizens participate. This type of system is often referred to by others as a free market, or capitalism. In a free enterprise system, you are allowed to spend your money in the way you want. You often have several different companies competing for your business, which often leads to lower prices and better quality products. You are also free to pursue any type of job or work that you enjoy.
