Social change is often thought to be driven by public and nonprofit sectors. This is true. But because of the nature of this work, they will always be constrained by funding challenges. In times where funds run dry, where can the social sector get its spare change from?
Enter the social enterprise. They gain revenue for mission-related purposes by producing economic value in a way that also creates value for society ([[creating shared value]]). Think, "bike shop that hires and trains people experiencing homelessness", or "coffee store that provides jobs for displaced refugees". The result is a charity-like organization that is self-sustainable, independent, and can theoretically outperform bureaucratic governmental initiatives or traditional donor-funded charities (don't take it from me, check out the writings of the father of social entrepreneurship, J. Gregory Dees himself.
There is some debate about the efficacy of social enterprises, but there have been examples of [[social innovation that scales]], some at a global scale.
