"All major countries would come together to negotiate a new world order, which accommodates multiple powers or blocs rather than a single hegemon, with rules that ensure that everyone – regardless of their political or economic system and state of development – behaves responsibly." Given Piketty's Thesis, and the threat of global anthropogenic climate disruption, this model, or one along its workings, would appear capable of responsibly aligning investment, trade and Development, along three axes, to improve global well-being: North-South America, Asia-Oceania, and Europe-Africa. To wit:



Mathematical Model and Simulation for "A Partnership for Development with the United States of America" that would articulate Private Sector and Public Sector entities pertinent to environmentally-friendly holistic socioeconomic development in the American Hemisphere, bringing together its 35 nations, in a concerted effort to reduce and eliminate the existing ominous welfare gap, led by the Private Sector, for profit. Model and Simulation developed in Excel in 1999, and subjected to its subsequent versions through Excel 2003 and its updates through 2014. Some macros may not work appropriately today. This is merely an structural example:

At the crux of world peace, and planetary rescue, would be tax reform, via Sole Consumption Tax (SCT), that would enable eradication of absolute extreme poverty and relative extreme poverty, through regular income redistribution ensuring the attainment of autonomous survival with increasing welfare potential for the poorest, that would irreversibly approach that of the richest, voluntary population stabilization, voluntary production and consumption stabilization, and carbon emissions stabilization.

The capitalization imbalance between the northern hemisphere, and the southern hemisphere, developed countries and the underdeveloped, and between OECD countries and the rest, suggests that something may be failing in the capital markets’ capacity to arbitrate investments: It would seem that it does not function effectively, and that the not so uncommon perception of increasing relative backwardness of the Third World is true. If so, beyond investigating its causes, it is necessary to investigate the attributes, achievements, and plans of existing multilateral and governmental poverty eradication and economic development organizations, and of their private counterparts, and the regulatory environment, in order to determine the need and opportunity for the creation of new private-public systems to increase the north-south investments rate.

A cursory analytical look at Thomas Piketty's Thesis clearly suggests that the intrinsic nature of Capitalism ensures that the rich will get richer and the poor poorer, ad infinitum, till annihilation of the poorest, in any society in any country, unless taxation through a sole consumption tax is used to regularly redistribute the wealth created in all societies, within societies, in such a way as to preempt consumption by the poorest from falling below the threshold of autonomous survival with monotonically increasing welfare potential, that would bring their share of wealth consumption irreversibly and asymptotically closer to consumption by the richest of the rich over time. This condition would not imply equality, only the trend to equality, but when perceptible, would ensure the possibility of harmonious socioeconomic development and peace. Absolute extreme poverty as well as relative extreme poverty would be eradicated, and planetary rescue could then be pursued, essentially through voluntary population stabilization, production and consumption stabilization, and carbon emissions stabilization.

Reflecting on the concerns of ordinary people about the serious environmental pollution we are experiencing today and its threatening effects on life on Earth, and the timid efforts of national governments and multilateral organizations to control and reverse it, I get to thinking that there is no sense in encouraging the creation of mechanisms, including not even in tolerating the use of the existing ones, enabling OECD countries (mainly developed countries) to continue emitting pollutants into the environment, whether they be gases, liquids, or solids, critically above the average global emissions by industry, geographic area, or country.
