One citizen, or a few, may be powerless if all the rest are determined to benefit from the imposition of unjust supranational rules. But this excuse cannot work for large numbers. Just imagine 10 million US citizens saying in unison: "I am just one powerless citizen. There is nothing I can do to change my government's policies!"

The collective income of all these people - the bottom half - is less than three percent of global household income, and so there is a grotesque maldistribution of income and wealth.

There exist better models of decisionmaking, for the governance of states, corporations and other large organizations, for example in Germany. We need to study such models and promising pathways on which our existing decisionmaking procedures can be gradually reformed.

A few hundred years ago, perhaps 85 or even 90 percent of humanity lived below a standard of living that today only 40 or 45 percent fail to reach. But at that earlier time only part of this poverty could have been eradicated, and this at substantial cost not only to the pleasures of the affluent, but also to their well-being and to human culture. In our time, nearly all severe poverty could be eradicated at a cost to the affluent that is truly trivial.

What we should do is require or at least permit innovators to license their green innovations free of charge in exchange for public payments based on the impact this innovation has on the environment - emissions averted or something of this sort.

I think one big improvement would be if we somehow made it cheaper and easier for developing countries to learn from the sad experience of some of the developed countries, and also from some of the positive experiences we have of building good transportation systems, like high-speed rail.
