Muhammad Yunus, the Bangladeshi economist, microfinancing pioneer and founder of the grassroots Grameen Bank, has not been resting on his laurels since wining the Nobel peace prize in 2006. The idea behind his multi award-winning idea of microcredit is that everyone is a natural entrepreneur. "Human beings are not born to work for anybody else," he says. "For millions of years that we were on the planet, we never worked for anybody. We are go-getters. So this is our tradition. There are roughly 160 million people all over the world in microcredit, mostly women. And they have proven one very important thing: that we are all entrepreneurs. Illiterate rural women in the villages ... take tiny little loans - $30, $40 - and they turn themselves into successful entrepreneurs." In the mid 70s, as a young economics professor, Yunus experimented with lending a mere $27 to 42 women in the village ... near his university. Banks would not lend to the poor ... and moneylenders charged extortionate rates. His experiment was a success, and he began to develop ... the Grameen Bank. The Grameen Bank today has nine million borrowers, 97% of them women. "They own the bank. It is a bank owned by poor women," he says. "The repayment rate is 99.6%, and it has never fallen below that in our eight years of experience." Part of his expansion into rich countries includes a program in the US: 19 branches in 11 cities, including eight in New York.
