I see the United States experiencing slow growth for the foreseeable future, say a decade or two. Contrary to popular opinion, the pace of technological innovation has been quite slow, as evidenced by the data. We are an aging society with a growing and apparently unfixable set of fiscal problems.
That said, I do see a few compensations.
First, there are more cheap entertainments than ever before, most of all through the Internet. I don't want to suggest this makes up for not having a job, or seeing no wage growth, but at the margin a lot of the fun on the Internet (including this symposium!) is free. The Internet also has strengthened a lot of social bonds and support networks.
Second, the United States has seen a lot of social progress over the last few decades, whether it be women's rights, gay rights, general tolerance, or any number of other issues. That has improved the lives of many millions. We also can see that crime rates have been falling for a long time and that makes a lot of aspects of life more secure and more enjoyable.
Third, I find it striking that American mobility peaked sometime in the 1980s. Today there are people moving to find jobs, but not at anything like previous levels in earlier downturns. Some of that results from "the problems are in many different places" and that's bad news. But some of it is also "being jobless today involves some greater cushions than in earlier times." Very few people are facing potential starvation. For instance many more men have working spouses. Durable goods have become more durable, or in other words your car is less likely to break down and that makes joblessness somewhat easier to bear.
