We have entered a new political era. For the past 40 years or so, we lived in the information age. Those of us in the educated class decided, with some justification, that the postindustrial economy would be built by people like ourselves, so we tailored social policies to meet our needs.

Our education policy pushed people toward the course we followed — four-year colleges so that they would be qualified for the "jobs of the future.” Meanwhile, vocational training withered. We embraced a free trade policy that moved industrial jobs to low-cost countries overseas so that we could focus our energies on knowledge economy enterprises run by people with advanced degrees. The financial and consulting sector mushroomed while manufacturing employment shriveled.

Geography was deemed unimportant — if capital and high-skill labor wanted to cluster in Austin, Texas, San Francisco and Washington, it didn’t really matter what happened to all those other communities left behind. Immigration policies gave highly educated people access to low-wage labor while less-skilled workers faced new competition. We shifted toward green technologies favored by people who work in pixels and we disfavored people in manufacturing and transportation whose livelihoods depend on fossil fuels.
