G8, G20 or ideally . . . G192. These economic summits are just wrong. 20% of the world's population (developed nations) uses up 90% of the world's resources. The World Bank, the IMF are functioning to increase empire - especially for the USA. I find the insights of the UN representatives from the rest of the world far more salient. I find this especially true for the women and girls in the world - who will feel the brunt of crisis much harder as the days, months and years go by.
The international system (like the US economic system) is broken and this is the best time to chuck it for a better system that serves the vast majority of the world, rather than a small, privileged portion.
