Too many big homes for too few two-parent families

In First Things, David Goldman has a very interesting (at least to me) piece about demographics and the housing bubble burst.

Now, consider this fact: America’s population has risen from 200 million to 300 million since 1970, while the total number of two-parent families with children is the same today as it was when Richard Nixon took office, at 25 million. In 1973, the United States had 36 million housing units with three or more bedrooms, not many more than the number of two-parent families with children—which means that the supply of family homes was roughly in line with the number of families. By 2005, the number of housing units with three or more bedrooms had doubled to 72 million, though America had the same number of two-parent families with children.....

If capital markets derive from the cycle of human life, what happens if the cycle goes wrong? Investors may be unreasonably panicked about the future, and governments can allay this panic by guaranteeing bank deposits, increasing incentives to invest, and so forth. But something different is in play when investors are reasonably panicked. What if there really is something wrong with our future—if the next generation fails to appear in sufficient numbers? The answer is that we get poorer....

We could put this another way: America’s housing market collapsed because conservatives lost the culture wars even back while they were prevailing in electoral politics. During the past half century America has changed from a nation in which most households had two parents with young children. We are now a mélange of alternative arrangements in which the nuclear family is merely a niche phenomenon. By 2025, single-person households may outnumber families with children.....

Unless we restore the traditional family to a central position in American life, we cannot expect to return to the kind of wealth accumulation that characterized the 1980s and 1990s. Theoretically, we might recruit immigrants to replace the children we did not rear, or we might invest capital overseas with the children of other countries. From the standpoint of economic policy, neither of those possibilities can be dismissed. But the contributions of immigration or capital export will be marginal at best compared to the central issue of whether the demographics of America reverts to health.

Life is sacred for its own sake. It is not an instrument to provide us with fatter IRAs or better real-estate values. But it is fair to point out that wealth depends ultimately on the natural order of human life. Failing to rear a new generation in sufficient numbers to replace the present one violates that order, and it has consequences for wealth, among many other things. Americans who rejected the mild yoke of family responsibility in pursuit of atavistic enjoyment will find at last that this is not to be theirs, either.
