Why Bubbles Are Perfectly Rational & Unavoidable
Most bubbles are the product of more than just bad faith, or incompetence, or rank stupidity; the interaction of human psychology with a market economy practically ensures that they will form. In this sense, bubbles are perfectly rational—or at least they’re a rational and unavoidable by-product of capitalism (which, as Winston Churchill might have said, is the worst economic system on the planet except for all the others). Technology and circumstances change, but the human animal doesn’t. And markets are ultimately about people.
Here are three thoughts about bubbles that I hope we all can keep in mind.
1. Bubbles are to free-market capitalism as hurricanes are to weather: regular, natural, and unavoidable. They have happened since the dawn of economic history, and they’ll keep happening for as long as humans walk the Earth, no matter how we try to stop them. We can’t legislate away the business cycle, just as we can’t eliminate the self-interest that makes the whole capitalist system work. We would do ourselves a favor if we stopped pretending we can.
2. Bubbles and their aftermaths aren’t all bad: the tech and Internet bubble, for example, helped fund the development of a global medium that will eventually be as central to society as electricity. Likewise, the latest bust will almost certainly lead to a smaller, poorer financial industry, meaning that many talented workers will go instead into other careers—that’s probably a healthy rebalancing for the economy as a whole. The current bust will also lead to at least some regulatory improvements that endure; the carnage of 1933, for example, gave rise to many of our securities laws and to the SEC, without which this bust would have been worse.
3. We who have had the misfortune of learning firsthand from this experience—and in a bust this big, that group includes just about everyone—can take pains to make sure that we, personally, never make similar mistakes again. Specifically, we can save more, spend less, diversify our investments, and avoid buying things we can’t afford. Most of all, a few decades down the road, we can raise an eyebrow when our children explain that we really should get in on the new new new thing because, yes, it’s different this time.
