This is misleading in parts, and flat out false in others.
Every lie and deception starts with a truth, that eventually gets twisted. Here is where this lie originated.
Throughout 2010, USA TODAY printed a series of articles that showed that several federal departments had substantially more workers earning $150,000+ (in pay and benefits) than they did even a few years ago. Somewhere in that series, USA TODAY wrote that this was about 30% more than the counterparts in the private sector were earning.
This lie has morphed into ALL government employees, and I can say it's honestly not true.
I have several friends, relatives, and associates who work in the state and city government. When I told some of them about this series of articles, they laughed and would say they wish they got paid that much. What state and local government often do is make up for the lack of salary by giving a halfway decent retirement package.
Finally, there are jobs in the public sector that just don't exist in the private sector, thus there's no proper comparison between public and private salaries. Police and fire, for example.
Is there reform that's needed in collective bargaining and public sector unions? It's a debate that should be had. But let's not take it out on the back of the majority of state and municipal workers who work hard doing the public good, and often for very little money.
