Another big problem with the pensions is that long ago some of the unions and other people got voters to agree that pensions could not be reduced put into their state constitution..... and nobody wants to be the person who tries to get the constitution changed...
Illinois is a great example from what I read.... they keep passing laws to change the pension but when taken to court they lose and have to go back to the old way... so, instead of passing a law change the constitution... but that will not happen since the politicians in place do not want to do it..
Instead of wasting their time trying to amend the constitution they can create new tiers of workers with less benefits.
