I find it odd that he is complaining about a resource limited organization not stepping beyond its goal to “show what success looks like”. Because it’s hard for a resource limited world to help that much everywhere at once.
That's not quite his complaint. His complaint is that despite the project being quite well funded (relative to others), they don't seem to take an active interest in measuring results that they can be accountable to. It is somewhat remarkable that they wouldn't though if the goal of the Millenium Villages is to show others 'the way'.
