“In the 1950s, industrial workers had become the largest single group in every developed country, and unionized industrial workers in mass-production industry (which was then dominant everywhere) had attained upper-middle-class income levels. They had extensive job security, pensions, long paid vacations, and comprehensive unemployment insurance or "lifetime employment." Above all, they had achieved political power… Thirty-five years later, in 1990, industrial workers and their unions were in retreat. They had become marginal in numbers. Whereas industrial workers who make or move things had accounted for two fifths of the American work force in the 1950s, they accounted for less than one fifth in the early 1990s--that is, for no more than they had accounted for in 1900, when their meteoric rise began… By the year 2000 or 2010, in every developed free-market country, industrial workers will account for no more than an eighth of the work force. Union power has been declining just as fast… By the year 2000 or 2010, in every developed free-market country, industrial workers will account for no more than an eighth of the work force. Union power has been declining just as fast.”
