Yes, fair, maybe it doesn't. But I think several factors do work in favour of the smaller organization in terms of it being a smaller target, having the operation based more on local relationships and trust networks, and being accountable for an overall smaller budget— it's harder to ignore 10k in bribes of if it's only half a million or so per year coming in from the west.

Anyway as I say it's not everything but I thought it seemed relevant to the GP post talking about NGOs and charity efficiency.
