Greg, I am an economist and would use some economic jargon to comment on your article and viewpoints.


Your analysis is reasonable in terms of adaptive expectations, based on past experiences. The likely problem with that is if there are structural changes occurring, then adaptive expectations may lose their explanatory power. In contrast, rational expectations may be handy to use to explain things.


Over the last 20 years or so, the world has undergone an enormous and powerful structural change, typified by the rise of very large developing economies, such as China and India. This kind of structural change in the world economy means the relative decline of the developed economies and the increase in the relative weight of the developing economies. Along with this structural shift towards the developing economies, technologies are also moving to the developing world.


While China, the most dynamic example of the rising developing economies, has its many problems, it also has its strengths to formulate and stick with a long term plan. The Chinese and Indians can be as innovative as the Americans, as long their talents are allowed to do so. You and the readers can draw conclusions.
