this publication does all it can to perpetuate lies.
check the womens/mens pay gap article.
still is same old stuff that takes all womens wages, all mens wages, and compares them. 
Doesn't correct for how many women are engineers as men, or parts of country, or working hours.
It's been disproven by real economic studies for decades, but this paper wants nothing more than to perpetuate it, and many other fallacies, like this deficit spending is the will of the people lie.
