Why are entrepreneurs considered both spark plugs and catalysts of the free enterprise economy?

Entrepreneurs are considered to be both spark plugs and catalysts of the free enterprise economy because of a number of reasons. Everybody benefits and profits when an entrepreneur becomes successful. When an entrepreneur opens his or her search for profits, the effects would be a chain of events where new products, greater competition, more production, higher quality, and lower prices for consumers can be observed. An entrepreneur is said to be a spark plug in the free-market for there is that vision of providing a product or a service that people are willing to pay for, combined with the ability to produce that product or service at a cost below the market sales price which propels him/her to take action. Capitalism will not work if it were not for the entrepreneurs who take the risks and start the businesses that produce the goods and services we all enjoy.
