"Advantages of a Market Economy
A market economy has several advantages:
Competition leads to efficiency because businesses that have fewer costs are more competitive and make more money.
Innovation is encouraged because it provides a competitive edge and increases the chance for wealth.
A large variety of goods and services are available as businesses try to differentiate themselves in the market.
Economic activity is encouraged because you need money to live and need to engage in economic activity (through employment or self-employment) to make money.
Freedom of individual choice is possible to the extent that the market provides options for work, developing a business, and purchasing goods and services (so long as you can afford them).
Disadvantages of a Market Economy
Market economies are also not without disadvantages:
Disparity in wealth and mobility exists in market economies because wealth tends to generate wealth. In other words, it's easier for wealthy individuals to become wealthier than it is for the poor to become wealthy.
Environmental damage results with no government regulations because it's usually more expensive to produce in an environmentally sound manner, which reduces profits.
There tends to be a reduced social safety net, including such programs as unemployment insurance, Social Security, and Medicare, because these programs are supported through taxation.
Poor working conditions can result due to a lack of government regulations because health and safety cost money, thus reducing profits.
Questionable priorities can result when the overriding decisions regarding production are profit-motivated rather than serving the needs of the people in society.
