Muhammad Yunus and the Grameen Bank have been awarded the Nobel Peace Prize. There's not much better than someone whose mouse trap is really better:
To ensure repayment, the bank uses a system of "solidarity groups." These small informal groups apply together for loans and its members act as co-guarantors of repayment and support one another's efforts at economic self-advancement. As it has grown, the Grameen Bank has also developed other systems of alternate credit that serve the poor. In addition to microcredit, it offers housing loans as well as financing for fisheries and irrigation projects, venture capital, textiles, and other activities, along with other banking services such as savings.
Many, but not all, microcredit projects also retain its emphasis on lending specifically to women. More than 96% of Grameen loans have gone to women, who suffer disproportionately from poverty and who are more likely than men to devote their earnings to their families.
