If you read the full report, and you compare by race men still make more. Childless white men make more than childless white women. Childless Hispanic men make more than childless Hispanic women. Childless black men and women make about the same. White women make more than Hispanic men.
Due to a larger ratio of white women : minority women compared to white men : minority women, it skews the "Women's earnings" up.
There are many reasons why various groups make 'more' or 'less' but it is kinda disingenuous what people try to 'prove' with this report.
