I came across websites at Iowa State University for complex adaptive systems and for agent-based computational economics maintained by Prof. Leigh Tesfatsion. He also recommends greater use of the United Nations and less resort to direct bombing of nations or places where innocents are made victims. Galbraith sees national taxation as a tool to reach his objectives.
Taxation is, of course, age old.
It has never lead to the results he seeks. In fact it is most often an instrument of oppression. Leigh Tesfatsion's pages appear to me to be in search of underlying aggregate forces which shaped the past and will influence the future. They do not seem deliberately aimed at values and change from bad values to good ones. The future of capitalism, democracy and the United Nations are, I think, very closely tied together.
