A half century ago America’s largest private-sector employer was General Motors, whose full-time workers earned an average hourly wage of around $50, in today’s dollars, including health and pension benefits. Today, America’s largest employer is Wal-Mart, whose average employee earns $8.81 an hour. A third of Wal-Mart’s employees work less than 28 hours per week and don’t qualify for benefits. There are many reasons for the difference—including globalization and technological changes that have shrunk employment in American manufacturing while enlarging it in sectors involving personal services, such as retail. But one reason, closely related to this seismic shift, is the decline of labor unions in the United States. In the 1950s, over a third of private-sector workers belonged to a union. Today fewer than 7 percent do. As a result, the typical American worker no longer has the bargaining clout to get a sizable share of corporate profits. (Source)Lamestream media, the Supreme Court, and your basic ignorant American all contend (or pretend) that organized labor is somehow a huge threat to the "proper" operation of the free market. It's a crock, like most of the nonsensical assertions of the defenders of the American way.
