For decades, workers migrated to big cities in America that promised abundant jobs and decent wages — in clerical offices in New York, at shipbuilding yards in Oakland, on auto assembly lines around Detroit.
Big, dense cities offered not just better pay for lower-skilled workers; cities offered them better kinds of jobs.
This is much less true today, as workers hurt by the decline in manufacturing know. Because of this, cities no longer offer low-skilled workers the economic advantages they once did, according to new analysis by the M.I.T. economist David Autor.
