Episode three introduces viewers to the concept of social entrepreneurism.

Episode three introduces viewers to Muhammad Yunus, known as the "banker to the poor," and one of the fathers of the concept of social entrepreneurism. With the simple but powerful realization that the poor need to be able to borrow money more than the rich do, Yunus founded Grameen Bank, which has today provided $3.8 billion in loans to 2.4 million families in Bangladesh and inspired similar credit operations in 100 countries. Leveraging the traditional craft of women in Rio de Janeiro, Maria Teresa "Tete" Leal founded a sewing cooperative called Coopa-Roca that produces high-quality, high-style clothes while maintaining fair labor practices for the women. Less glamorous as an occupation, but critically important, garbage collection is often a neglected service among the poor. In Peru, Albina Ruiz worried about the health impact of living in the filth of uncollected waste. Creating a micro-enterprise to do the job that the government was ignoring, Ruiz now has projects in 20 cities that provide garbage collection for over three million residents and employ 150 people. Creating businesses that break the cycle of poverty is the genius of social entrepreneurs.
