The hollowing-out of the middle of the labor market—where stable, mid-skill, mid-wage jobs have been disappearing while both low-wage service work and high-skill professional work grow—leaving a barbell where a bell curve used to be.
Labor market polarization is the structural signature of an economy in which automation removes the routine cognitive and manual work that once formed the stable middle of the employment distribution.
Martin Ford identifies it as the seventh of his seven signals: the labor market is not simply losing jobs at the bottom; it is losing the middle-skill, middle-wage jobs that formed the foundation of the American middle class—clerical work, manufacturing supervision, bookkeeping, data processing, certain categories of skilled trades—while both the low end (personal service, care work, tasks that resist automation because they require physical presence and social interaction) and the high end (creative, managerial, and technical work requiring flexible expertise) continue to grow. The result is a barbell distribution where a bell curve used to be. This pattern was first documented in the early 2000s by economists David Autor, Frank Levy, and Richard Murnane, who described it in terms of
