I think the demographic argument is that following this coming generation, China will plateau and then decline, in part because of the number of unmarried males. The increase in productivity will alleviate this somewhat, but at some point in the not so distant future, at least on a geopolitical historical scale, all of those children that the Chinese didn't have will be missed.
No I understand the demographics math. My parents had 4 siblings each, and yet I + most of my cousins are only children. Our kids have four grandparents each fighting for their attention... So obviously when they get older, they directly/indirectly will have to provide for them. I still say one engineer will be far more productive than four farmers.
there is nothing to be arrogant about here, just a fact, to be recognized as a pioneer as what heech wanted u have to contribute for the betterment of mankind, which is not the case here, just for quoting evidences sake, name any major chinese IT co.s and look inside will find an exact replica of a western IT co. product, even heech is not proud of it
