Free Enterprise involves the free exercise of any economic activity, freedom of labor, craft or profession beyond freedom of contract. In a broader concept, work can be understood as the ordered array of man's energies toward an economic end.
Free enterprise must be understood as the possibility of private action in the economic domain, without the embarrassment of the public power. It is the portion of freedom, unfolded as freedom to the exercise of economic activity. And because of that is so important.
