Do women do as well as men… as long as they don't have kids?

“Economic odds stacked against mothers,”Most parents are simply not able to have it all, regardless of where they are on the income spectrum.A recent study of business school graduates from the University of Chicago found that in the early years after graduating, men and women had “nearly identical labor incomes and weekly hours worked.” Men and women also paid a similar career price for taking off or working part time. Women, however, were vastly more likely to do so.As a result, 15 years after graduation, the men were making about 75 percent more than the women. The study — done by Marianne Bertrand, Claudia Goldin and Lawrence Katz — did find one subgroup of women whose careers resembled those of men: women who had no children and never took time off.
