Are Things Really That Bad? Actually, No

Before I begin, please note: I am not a pessimist. I am not short the market, and I think the world is far more likely to muddle through than to fall apart. Nonetheless, I now believe the future will be far more irresponsible and stupid than I once did.

I am increasingly worried that human success and failure are ruled by taste — the demand side, in economic terms. If there are fewer beautiful and charming residential post-World War II neighborhoods, it is because most people do not want to live in them. If there are fewer movies today with the dramatic impact and compositional rigor of “Citizen Kane,” it is because people do not very much want to see them. It is not that it is too difficult or expensive to make another “Citizen Kane.”

Again, this is not an argument for pessimism. Hollywood movies may be worse, but television programs are much better. Neighborhoods may look less interesting, but the insides of homes are more comfortable. For every potential lost Baroque concerto, there are gains in other areas of life.

Still, it is striking how much the quality of taste can decline — and stay there for long periods.

Social contagion plays a significant role in this process. That is, when some people become interested in a particular genre, many others may follow: Think of the rise of Beatlemania. The process also works the other way: Think of the decline of disco.

The question is why some particular tastes decline, and others rise. There are probably deep structural explanations, but for the most part those reasons are not transparent to our understanding. For all practical purposes, many shifts in cultural tastes are random.
