If women were truly paid $0.77 for every dollar earned by men for truly equivalent work as the President has claimed multiple times during his administration, most recently during the 2014 State of the Union address, then the smart businessman would simply fire all the men and replace them with women. After all, what evil capitalist (as liberals/progressives portray them) would willingly pay 23% more than needed for labor?
We know that the 23% gap is misleading at best, but let's say the Congress was able to pass the Paycheck Fairness Act. That law would simply line the pockets of lawyers who file lawsuits they know they can't prove in court, unless someone in the company is stupid enough to put it in writing, because what they're really looking to do is extort a settlement from the company. That means the law's crowning achievement would be to increase the cost of hiring women. What do you get as a result? Fewer women hired into comparatively higher-paying jobs where a potential lawsuit would carry with it more zeroes. So we have yet another example of political intervention making things worse, not better. And this situation doesn't apply to just women. This applies to virtually every protected class.
The safest person to hire from a legal exposure perspective is a white, heterosexual, Christian male with no disabilities and no military service record. And what kind of person do we see dominate the boardrooms of Corporate America?
