Everything else in the debate is BS (perhaps the Oscar for BS could go to these geniuses who claim that taxpayers don't pay for the compensation of public sector workers).
So it doesn't matter if you can find a study saying public employees are over or under paid or have higher or lower benefits. It doesn't matter if you compare apples to apples or apples to hedgehogs. It doesn't matter if the unfunded pension liabilities are mostly structural or cyclical.
This is just straight up political payback. I wonder what the public sector union bosses expected would happen if the Republicans ever figured out what was going on and got hold of enough political power to do something about it?
