Population Doom

Mark Steyn continues to run the numbers on world's future population and they don't look good:

"Demography doesn't explain everything but it accounts for a good 90 per cent. The "who" is the best indicator of the what-where-when-and-why. Go on, pick a subject. Will Japan's economy return to the heady days of the 1980s when US businesses cowered in terror? Answer: No. Japan is exactly the same as it was in its heyday except for one fact: it stopped breeding and its population aged. Will China be the hyperpower of the 21st century? Answer: No. Its population will get old before it gets rich."
