In manufacturing, for example, Ford, Chrysler, General Motors, Caterpillar and Navistar (formerly International Harvester) all pay many of their new workers much less. In some of these two-tier structures, the new wage may be as little as half the old one. In addition to this rapid change, the companies also seem to be reducing the ranks of highly paid workers through slow attrition.

Here is another change that might be a broader sign of a pending reset: A heavy burden of adjustment in the overall labor market is being borne by the young. Wages for the typical graduate of a four-year college have dropped more than 7 percent since 2000, and the labor force participation rate of the young has been falling. One consequence is that young people are living at home longer and receiving more aid from their parents. They also seem to be less interested in buying their own homes.

All of these factors could indicate that our economy is evolving into one that will offer far less favorable long-run wage prospects. Much research has shown that the effects of a recession can be pernicious for decades: Earning a lower wage in earlier years is predictive of lower wages through the rest of one’s career. While we are seeing economic problems for the relatively young, they will eventually become dominant earners in the economy and the major force behind broader statistics.

In short, are these economic problems transitory, or are we glimpsing the beginnings of a grimmer future?
