"Global problems will need better global solutions. In the wake of the second world war, we managed to create an IMF [International Monetary Fund], a World Bank, a WTO [World Trade Organisation], a Marshall Plan. We had the capacity with vision and determination to create institutions based on the principle that for prosperity to be sustained it had to be shared and we had to have mechanisms by which we brought the whole world into this enterprise.
"I think we need the same vision now to say the IMF was built for the days when you were dealing with balance of payments problems of individual countries in essentially a national set of economies. Now we've got a global market place, global competition, global flows of capital, global sourcing of goods.
"The institutions you need to deal with these problems are going to be quite different for this new era, so we must shape them."
Well, that's great, but if the G20 is capable of the vision and agreement to achieve these new institutions, what guarantee is there that they will not be as divisive and flawed as the IMF and World Bank and the structural adjustment policies they forced developing countries to adopt? Ironically the IMF, controlled by rich nations, has in the past pressured developing countries not to intervene to protect their banking systems, saying they must be allowed to fail; when it suits them, rich countries do not follow the rules they impose on others.
The answer is, of course, that there is no guarantee. Even if it works, the vision is still for perpetual growth on a planet that already cannot support the demands placed upon it.
While the Simultaneous Policy campaign cannot offer guarantees about the policies developed in the democratic space it provides, the fact that people around the world are invited to participate in the process, shape the policies and vote on them does provide checks and balances missing from the rich countries' club.
The G20 will see campaigners united in opposition on the outside and leaders inside protecting their individual national interests when we need coordinated, coherent and effective action.
