Susanna Mancini used to be successful as a lawyer and well paid for it. But her career eventually succumbed¹ to her husband's even bigger success. She quit in 2005 when her six-digit income was overtaken by his seven-digit one.

苏珊娜•曼西尼曾是一名成功的律师，而且收入不菲。但最终她的事业还是败给了更为成功的丈夫。2005年当她六位数的收入被丈夫七位数的收入赶超后，她便退出了职场。

She is far from alone, according to a new study from the Federal Reserve, due to be published shortly.

It shows that between 1993 and 2006, there was a decline in the workforce² of 0.1 percent a year on average in the number of college-educated women, with similarly educated spouses³.

That contrasts with growth of 2.4 percent a year between 1976 and 1992.

In 1975, college graduates of both sexes were making 43 percent more than non-college graduates. By 2008, the figure had risen to 92 percent for men and to 70 percent for women.

"In the last 20 years, wages for highly educated males increased so much that they dwarfed⁴ the family's second income, usually the one of their wives," said Albanesi, who co-authored the study with Columbia University graduate student Maria Prados.

"The result was that sometimes married women exited the labor⁵ force mid-career, exactly around the time their husbands are promoted to more senior roles. They stopped getting income they didn't need and so they left the labor force forever."
