The answer might be found in the vision of global wealth redistribution that has been advocated by Obama's top science adviser, John P. Holdren.
In 1973, Holdren co-wrote a book -- "Human Ecology: Problems and Solutions" -- with Anne H. Ehrlich and Paul R. Ehrlich, author of the 1968 bestseller "The Population Bomb."
The book called for "de-development" of the United States and global redistribution of wealth.
"A massive campaign must be launched to restore a high-quality environment in North America and to de-develop the United States," Holdren and the Ehrlichs wrote on page 279 of the book. "De-development means bringing our economic system (especially patterns of consumption) into line with the realities of ecology and the global resource situation. Resources and energy must be diverted from frivolous and wasteful uses in overdeveloped countries to filling the genuine needs of underdeveloped countries."
"Redistribution of wealth both within and among nations is absolutely essential, if a decent life is to be provided for every human being," Holdren and the Ehrlichs wrote.
In 1995, Holdren argued for "a world of zero net physical growth" in an essay titled "The Meaning of Sustainability: Biogeophysical Aspects" that he co-authored with Paul Ehrlich and Gretchen C. Daily. The essay was published in a book compiled by the World Bank.
"We know for certain, for example, that: No form of material growth (including population growth) other than asymptotic growth is sustainable," Holdren, Ehrlich and the Daily wrote.
"This is enough to say quite a lot about what needs to be faced up to eventually (a world of zero net physical growth), what should be done now (change unsustainable practices, reduce excessive material consumption, slow down population growth) and what the penalty will be for postponing attention to population limitation (lower well-being per person)," they wrote.
The essay included a table titled "Requirements for Sustainable Improvements in Well-Being." One of these requirements was: "Reduced disparities within and between countries." The "rationale" for doing this, the authors wrote, was, "The large gaps between rich and poor that characterize income distribution within and between countries today are incompatible with social stability and with cooperative approaches to achieving environmental sustainability."
Is it at all surprising that a president who would hire the author of these words as his top science adviser would pursue policies that will give U.S. manufacturers an incentive to relocate to developing nations and that will take tax dollars from American workers and give them to the governments of those nations?
For Obama's science adviser, Obama's trip to Copenhagen must be a dream come true.
