Why women are out-earning men

'Women are poised to become America's biggest breadwinners.

The tipping point is a generation away, assuming women's economic power keeps rising as expected. But already, the trend is stunning enough that TIME made it the subject of its current cover.

"Almost 40% of working wives out-earn their husbands," noted Liza Mundy, author of "The Richer Sex"--both the cover story and a new book that goes by the same title--at a breakfast in New York City, hosted by TIME and Fortune.

Why such rapid advancement? The Pill, Mundy said, helped spark the trend 50 years ago: Newly able to delay marriage and childbearing, women began focusing on their careers. America's shift to a service economy also favors college grads, who increasingly tend to be female. Today, women make up 60% of U.S. college classes and earn more masters and doctorate degrees than men.

What can stop women from out-earning men in more than 50% of U.S. households? "Nothing that I can see," Mundy, who writes for the Washington Post (WPO), told TIME Executive Editor Nancy Gibbs at the breakfast. Some industries, such as veterinary medicine, are so populated with women that few men are now entering them, she said. She calls the phenomenon "gender pollution." In 25 years, law and medicine may well be female-dominated.'
