Planners vs Searches: Easterly's book worth reading

I am reading a book that I suggest for anyone interested in the cause of making a difference among the global's poor and forgotten.  Easterly is a economics prof at NYU and involved in other things as well -  He is not too high on the "big plans" of ending poverty and offers a fine critique of even

"Sixty years of countless reform shemes to aid agencies and dozens of different plans, and $2.3 trillion later, the aid industry is still failed to reach the beautiful goal.  The evidence points to an unpopular conclusion: Big plans will always fail to reach the goal"

Easterly draws 2 different kinds of people when they look at global poverty: The 'planners' vs the 'searchers' -

"The Planners:  determine what to supply,  Searchers find out what is in demand.  Planners apply global blueprints, Searches adapt to local conditions.    Planners at the top lack knowledge of the bottom, Searches find out what the reality is at the bottom.    Planners never hear whether the planned got what it needed, Searches find out if the customer is satisfied...."

This is what I really like --

"The Planner thinks he already knows the answers; he thinks of poverty as a technical engineering problem that his answer will solve.  A Searcher admints he doesn't know the answers in advance: he believers that poverty is a complicated tangle of social, political, historical, institutional, and technological factors...".
