Make promises someone else will pay for

Blue Virginia has a post that sounds like a Tea Party thought - complaining about politicians making promises someone else will pay for.
Isn't that the problem Tea Party members see with federal spending, Social Security, Medicare, Medicaid, et al? Politicians spend for today and tomorrow's children will pay. And tomorrow is a lot closer than it used to be.
Changing the rules for state employees will be hard. But it's just joining the rest of the world, where retirement returns are not guaranteed.
If it's not fair for these employees to lose their defined benefit, than is it fair for taxpayers without defined benefits be forced to pay more taxes? To pay for someone else's promises in the past?
Don't just fuss at current Ponzi schemes. Democrats had their hands in the cookie jar for years.
