We have a World Bank and an International Monetary Fund run like TNCs by a hierarchy of rich-state shareholders. First let them argue for a transaction tax. Small groups of 'experts', against whom there can be no appeal, adjudicate on trade disputes. Distortions' of free trade could eventually include almost anything, from public health, to education or transport services. Other non-private matters, like decent air to breathe or reasonable conditions of work, are considered irrelevant to trade.
World government has to be reordered, or perhaps established for the first time.
As this is done we should remind ourselves that democratic government is not the same thing as the state bureaucracy. The latter has, by and large, aligned itself with globalization, set itself against the people and lost all political credibility. The former has to represent the people's will or it is worthless. Take one, small example that's particularly close to some of our hearts. Governments offered this pledge to the UN Social Summit in Copenhagen but have not yet redeemed it.
