If you wanted to find out this information, you could've looked it up yourself to prove me wrong. But you either didn't bother or found out that I am right. Now, here are a few links to public pensions in America. These are the exact type of pensions I was talking about. In the first link I want you to notice that it is Rahm Emmanuel who is calling for pension reform. Try to actually read the article. He says that if nothing is done to change the way the Chicago public pension is, that he will have to raise property taxes by 150% to pay for the unfunded promises. I'm sure you're a big Rahm supporter, that's why I cherry picked this particular article. And please don't go all 3rd grade on me and say that it is a city pension not a state. The burden still falls on the taxpayer and I'm not going to google every state pension in America. At last check, Illinois was only 54% funded on its public pension funds.

Here is an article about how New Jersey was able to change their pension plan under Gov. Christie because it was impossible to pay for. Also notice that democrats in the state agreed to it because they new it was bankrupting the state.

Here is an article about California woes. It is a CNN article so I'm sure you're okay with it. Notice that they call for California to make pension reform just like Scott Walker did in Wisconsin. Notice also that the article states that people aren't even talking about Walker's pension reform anymore because it worked.

Connecticut, Kansas, Kentucky, Massachusetts, Oklahoma, Rhode Island and West Virginia are all less than 67% funded. You can look them up if you want. I am done debating you on this. I have provided you with more states just like you asked. Until you can show proof that these unfunded promises will not cost tax payers extra money when they cannot meet the payroll, then you have no point.
