This is a spectacular summary of the macroeconomic trends Shanta. I think that you're placing too much emphasis on the role of government and policy in Africa's transformation, however. Certainly, the quality of the enabling environment provided by governments through investment in infrastructure and rationalization of bureaucratic procedures has a significant impact on growth. But the private sector plays an equally critical role. At that level, we've seen innovation, pursuit of new markets, and new forms of private sector organization driving growth. It's impossible to completely separate these two necessary ingredients to growth, but it would be a mistake to ascribe too much importance to one or the other.
