>reliable source that explains it
You're going to have to elaborate on "reliable source."
From an NPR interview concerning a report from the Association of University Women, a feminist organization: "After controlling for several relevant factors, they found that the wage gap narrowed to only 6.6 cents."

"How much of that is attributable to discrimination?" "We're still trying to figure that out." Do tell.
In fact, according to data from Census Bureau, "unmarried women who've never had a child earn more than unmarried men"

From "An Analysis of Reasons for the Disparity in Wages Between Men and Women" prepared for the U.S. Department of Labor in '09:

>This study leads to the unambiguous conclusion that the differences in the compensation of men and women are the result of a multitude of factors and that the raw wage gap should not be used as the basis to justify corrective action. Indeed, there may be nothing to correct. The differences in raw wages may be almost entirely the result of the individual choices being made by both male and female workers.
So, as with many good talking points, this is a game of statistics lacking important control factors. It's not exactly surprising that men are going to work on oil rigs, which is why the "77 cents" talking point is a brilliant piece of omission and great example of how statistics can be misused.
The purported "women's wage gap" virtually vanishes, and in fact it's a male wage gap in certain demographics, when you have proper controls for career decisions.
In summary: there is no wage gap when you compare apples to apples. If you are talking about women's career choices, then by all means encourage your daughter to be a professional in a high paying sector, as opposed to the low-paying education and health care sectors.
Or you could encourage her to join the lucrative fields of logging, piloting, construction or roofing, steel mill work, trash collection, mining, etc. where there is a very clear and distinct gap. They pay well.
