Social entrepreneurship refers to the process of employing market-based methods to solve social problems (e.g. poverty, environmental degradation, health care and education access, sanitation, unemployment). To date much has been written about how social entrepreneurship is revolutionizing the social sector by encouraging both greater innovation and financial sustainability. The ubiquity of social problems is undeniable, and the promise of social entrepreneurship is inspiring, but taken together these facts raise an important question for aspiring social entrepreneurs. If social problems are obvious and plentiful and social entrepreneurship provides a fruitful way to address such problems, why do we not see a greater degree of social entrepreneurial activity in our societies?
