Women with doctorate level degrees make as much their male counterparts with an undergraduate degree. From ThinkProgress.org:
Kay Steiger pulls out this chart from Georgetown’s Center on Education and the Workforce, which notes that, when it comes to lifetime earnings, women with a Ph.D. make as much as men with a B.A., while men with some college but no degree make about as much as women who have completed college.
The study [pdf] notes: “At all levels of educational attainment, African Americans and Latinos earn less than Whites.”
