Yet entrepreneurs also perform other functions that generate value. Any venture—including a restaurant or hardware store— through its presence in a competitive market is generating some increase in the private value captured by others. By offering new jobs, they keep existing companies from underpaying their employees; by offering new goods and services they keep existing producers from overcharging otherwise potentially vulnerable consumers. The existence of entrepreneurial activity in markets and the eventual reinvestment of residuals do nothing less than create the possibility for economic growth and social progress.
