FROM the 1940s to the 1970s, organized labor helped build a middle-class democracy in the United States. The postwar period was as successful as it was because of unions, which helped enact progressive social legislation from the Civil Rights Act to Medicare. Since then, union representation of American workers has fallen, in tandem with the percentage of income going to the middle class. Broadly shared prosperity has been replaced by winner-take-all plutocracy.
