Explain how consumer sovereignty operates in a marketplace to determine the success or failure of an entrepreneur

In the market place entrepeneurs compete for the dollar of the consumers. They are willing to interchange goods or sevices for money. The success or failure of an entrepreneur depends on how consumers approve or disapprove the products or services offered by entrepreneurs. If the product or service is seen as good or high quality then that entrepreneur will surely have high demand and will continue in the market place. If the product or service is seen as bad  or bad quality then that entrepreneur will disappear.
