I ALMOST agree with you. Yes, we should not have top-down solutions like Jeff Sachs is proposing. However, I don't think the free market will solve the problem by itself without a few reforms withing each country. Particularly land reform. So long as the land and the rent it yields is monopolized by speculators and big industry, economic growth will always be lop-sided. By using smart land reforms such as land value taxation, countries can fix the economic problems caused by monopolization of resources.
