Bill Easterly complains of fatigue in discussing whether aid works with Jeffery Sachs. I agree. Sachs’ ‘Millennium villages Project’ for example  was something that could only have been conceived by someone who had little sense of the history of the failure of these types of projects. Look back to the ‘development villages’ of the 1960s in Africa. Economic Development  comes from people’s capacities, motivations and energy. It simply cannot be done through outside (charitable) cash assistance, and the larger the number of assistance providers the more dysfunctional it becomes. The recent history of Africa shows at last some increase in indigenous capacity and motivation, and the diaspora is investing – eg in Somalia expatriate Somalis are way ahead of the aid agencies in trying to put the economy on the road to recovery.  Diasporans at least have the cultural affinity with the beneficiaries, the motivation to succeed and to the take greater investment risks than aid agencies, (or general foreign investors).
