Why is it acceptable to you to steal from people?   Because that is precisely what you are advocating.   And no the problem isn't the 'pension system' its legislators trying to spend 100% in now money without a plan that goes beyond two years.    I see it at school districts and cities all the time.   They get 'free money' to do this cool thing or this great program.   They take it on and in 2-3 years the 'free money' runs out but rather than cut that 'cool program' they start stealing from other areas of the budget to keep funding it and the two biggest areas that they steal from are employee compensation and employee retirements.  And part of the reason for it is taxpayers like yourself who demand the cool program be kept and demand no taxes are raised to support it.   

Here's the reality the taxpayers got work for immediate payment and promises of more.  It is theft to renege on the promises of more just as it would be theft if you refused to pay the remainder on a roof job.
