Do they say in the Windy City, Chicago:  Don’t bring a tired, and rebutted, argument to a policy discussion?   When, even if  the did Dim Won, a/k/a Barack Obama would not understand it anyhow, from Dim Won’s State of the Union, 3014, via Robert Stacy McCain:

You know, today, women make up about half our workforce, but they still make 77 cents for every dollar a man earns. That is wrong, and in 2014, it’s an embarrassment.
Women deserve equal pay for equal work.
You know, she deserves to have a baby without sacrificing her job. A mother deserves a day off to care for a sick child or sick parent without running into hardship. And you know what, a father does too. It is time to do away with workplace policies that belong in a “Mad Men” episode. This year let’s all come together, Congress, the White House, businesses from Wall Street to Main Street, to give every woman the opportunity she deserves, because I believe when women succeed, America succeeds.

Maybe Dim Won just didn’t say deserve often enough?  Simply saying the word deserve, over and over, does not make it so.

Reax:

So here we have a myth (women “still make 77 cents for every dollar a man earns”), a slogan (“equal pay for equal work”), and a number of vague rhetorical gestures toward policy to overcome a mythical disparity in accordance with an egalitarian slogan.

Thomas Sowell has made a cottage industry of debunking this bogus statistic. Dean Kalahar drew on Sowell’s research for the 2012 column “The female wage gap is a major economic myth.” Most recently, this past August, feminist Hanna Rosin joined the party in the Slate column “The gender wage gap lie.”

Men and women are different. They make different decisions with different economic outcomes.
