The importance - and potential corruption - of microcredit

I spent the last two days at a workshop for small producers, mostly agricultural, in Honduras. (I'll write something in the next day or two; it was interesting, even as I drowned in a 13-hour day of Spanish immersion.)
But a key issue was access to capital, even in tiny amounts. Doug Saunders' microcredit piece in the Globe today offers a useful perspective.
