If population starts to decline, we'll need some fundamental changes to the economic system. It's actually worse than that, since it's not the population as a whole, but, rather, the productive, working-age population. The US (and perhaps the "West" as a whole) is already on the precipice, if not already tipping over, with Baby Boomers hitting retirement age. Even when the more patent Ponzi scheme of Social Security collapses, it won't solve the underlying economic problem, that so few will have to support so many.
