Of course, the unemployment rate, at about 6 percent of the labor force, is not exceptionally high by historical standards, and one can debate the degree to which structural change and other factors may have affected the level of employment that can be sustained without overheating the economy.
Assessing the amount of slack in the labor market is very difficult and ultimately a matter of judgment. Reasonable people can certainly disagree. However, my sense is that, when one looks at the full range of information available, the labor market looks (if anything) weaker than a 6 percent unemployment rate suggests.
