“Our world is overpopulated.” If you repeat something often enough, it becomes “truth”. In 1968, Paul Ehrlich wrote The Population Bomb, warning that we’d all soon be fighting over food, space, and power as the earth sagged under the weight of all those darned people.
He was wrong, of course, and not just wrong: spectacularly wrong. It didn’t keep him from being a celebrity or from his ridiculous notion from being believed. But he was still wrong.
In What to Expect When No One’s Expecting: America’s Coming Demographic Disaster, author Jonathan V. Last attempts to point out the fallacies of Ehrlich and his ilk. Last is clear: our world is not overpopulated; we are vastly under-populated, and it’s a problem. He goes so far as to say that America has a self-imposed “One-Child Policy” that is leading us to demographic disaster.
Last is chiefly concerned with the problems under-population will cause America, but he uses several other countries to illustrate where we are headed. There are a lot of numbers in this book: financial figures about the costs of raising children, population numbers, fertility rates, the changing age of marriage. The conclusion doesn’t get lost in all the numbers: we don’t have the ability – population-wise – to take care of ourselves. That is, with programs like Social Security and Medicaid requiring a vast army of workers to keep them propped up and paying out, we can’t keep up. And if there aren’t enough workers to pay into these systems, there certainly aren’t enough people to take care of Grandma and Grandpa as they age and need more and more care. (more…)
