Even in a relatively prosperous age — for all of today’s woes, we have left behind the dark, satanic mills and workhouses of the 19th century — this decline of the middle class is more than an economic issue. It is also a political one. The main point of democracy is to deliver positive results for the majority.
All of which is why understanding what is happening to the middle class is urgently important. There is no better place to start than by talking to David Autor, an economics professor at the Massachusetts Institute of Technology. Autor is one of the leading students of the most striking trend bedeviling the middle class: the polarization of the job market. That is a nice way of saying the economy is being cleaved into high-paying jobs at the top and low-paying jobs at the bottom, while the middle-skill and middle-wage jobs that used to form society’s backbone are being hollowed out.
