Every thing will not be "Just Fine".

Your "great statistician" has a very narrow minded view of humanity. "Extreme Poverty" still exists. As the world population nears 11 million, stress increases. Those economies in Asia are already stressed and are very unstable. China rich ruling class is pumping billions into to the Chinese markets to pump them up, and prevent collapse. They can't do that forever. We are seeing the Warning signs now. The top heavy government of China will topple, much violence will follow. Over population will add even more stress on resources and on their economies. When that happens more little green balls will fall of his pat little graph. Over population will push already unstable stressed societies past the breaking points. Your great statistician is not seeing the whole human picture.

Violence will explode in those collapsing economies and cultures. I am not even talking about what natural disasters will do to these stressed over populated areas. Those disasters will cause even more of those little green balls to fall off that nice graph. Large sea level stressed populations are very subject to natural disasters. Many will die needlessly. Remember that 2004 earthquake ball??

Those shift in income numbers are shallow. They may be true, but that is not enough to prop up unstable economies and cultures. Those small income increases will vanish with the slightest down ward changes.

Your great statistician is not seeing the whole picture. His propaganda is promoting modern technology, corporate control in the world.
