Ending that with the "labor shortage" bit really undermined the rest. I read that in much of India it's a faux pas to buy a washing machine rather than hire the little old lady down the block. Labor shortages drive technological innovation, while labor surpluses lead to desperate workers taking menial jobs which are beneath their potential as human beings, as well as Luddism.
My hypothesis is that population is self-regulating in some way, be that socially or evolutional.
Personally, I really do think the fact that people put their careers before reproducing, therefore leading to problems later on is why there are fertility problems amongst developed nations. A huge number of people here in the UK don't have children until very late on and then have to rely on IVF which is not a flawless process.
The less "developed" (which is ironic) nations have less of a fertility crisis [1].
At the risk of sounding like some crazy hippy, this is all down to the short-sightedness of capitalism and globalisation self-destructing under its own rules. I think the article you linked neatly describes the arrogance that people should be able to control fertility rates.
