The interesting thing is, while we die of diseases of affluence from eating all these fatty meats, our poor brethren in the developing world die of diseases of poverty, because the land is not used now to grow food grain for their families.

A half century from now, our grandchildren are likely to look back at the era of mass employment in the market with the same sense of utter disbelief as we look upon slavery and serfdom in former times. The very idea that a human being's worth was measured almost exclusively by his or her productive output of goods and services and material wealth will seem primitive, even barbaric, and be regarded as a terrible loss of human value to our progeny living in a highly automated world where much of life is lived on the Collaborative Commons.

Though it is not as eloquent as the French and U.S. constitutions, it is the first governing document of its kind to expand the human franchise to the level of global consciousness. The language throughout the draft constitution speaks of universalism, making it clear that its focus is not a people, or a territory, or a nation, but rather the human race and the planet we inhabit.

We're finally going to get the bill for the Industrial Age. If the projections are right, it's going to be a big one: the ecological collapse of the planet.
