> Given that approx. 140 mio people in Bangladesh borrowed micro loans from him he must have had some influence on it.

That's a little far fetched. I am one of the 140 mil and I do not recall borrowing from him (or anyone I know). As novel as the idea of micro financing is, realistically it has little impact on poverty reduction in Bangladesh, the RMG and manpower export sector has more stake in the claim.

The sanitation revolution can be attributed to Sir Fazle Hasan Abed[0], the founder of BRAC[1].
