Seems like the OP was intending his diatribe to refer to federal workers, but then he specifically added in municipal workers, teachers, firefighters, etc. With that in mind, I can say firsthand that he's full of shit.
I'm a public employee, I happen to work for state government. State workers here have had their pay frozen since (IIRC) 2008. Pay freezes are tentatively scheduled to end in FY 2014, which for half of the workers is calendar year 2015. That's about 8 years of pay freeze, during which cost of living has gone up significantly.
Also during that time we've been subject to furloughs amounting to approximately 5% of pay per year.
Add in that in 2011 we took a 2.5% pay cut.
Oh, also add in that mandatory retirement contributions have gone up about 3%.
Don't forget that health premiums have gone up 100%.
Did I mention that those increased health premiums are also for worse coverage? Deductibles are also up 50-100% for PPO plans.
We're working on skeleton crews because we're prohibited from hiring, so workload has gone up.
Oh, and my agency is sitting on a seven-figure surplus because we've been forced to flat budget even though we have licensing and permit funds available.
A Grade 37, step 1, which is a mid-tier professional, should make about $50,526 per year. After all of the cuts they make about $45,520. From the time the cuts started to the time they are scheduled to end that person will have lost a total of $82,409 to the cuts, or about a year and a half of salary, plus they will still be at step 1 and about 8 years behind on the pay scale.
Oh, and we don't have a personal income tax here (it's prohibited by our constitution), so the public employees are bearing the burden of an unconstitutional income tax with no assistance from any other sector.
But that's cool, I mean, it is about time we contributed in some way, right? /sarcasm
