What's Good for GM...

Read Krugman.

In 1968, when General Motors was a widely emulated icon of American business, many of its workers were lifetime employees. On average, they earned about $29,000 a year in today's dollars, a solidly middle-class income at the time. They also had generous health and retirement benefits.

Since then, America has grown much richer, but American workers have become far less secure.

Today, Wal-Mart is America's largest corporation. Like G.M. in its prime, it has become a widely emulated business icon. But there the resemblance ends.

The average full-time Wal-Mart employee is paid only about $17,000 a year. The company's health care plan covers fewer than half of its workers.

True, not everyone is badly paid. In 1968, the head of General Motors received about $4 million in today's dollars - and that was considered extravagant. But last year Scott Lee Jr., Wal-Mart's chief executive, was paid $17.5 million. That is, every two weeks Mr. Lee was paid about as much as his average employee will earn in a lifetime.
