Let me put it this way---
1) A man comes to you when you are 22 and graduating from college and says:
"Work for me for 30 years and I will put aside $1000 a year for your retirement."
And you agree to the deal. You sign employment forms. Legally, those forms are the basis of a contract. That contract can be enforced in court.
Thirty years later the same man says to you -- I didn't put your $1000 in the bank every year. I spent it. The company is now bankrupt and I can't pay you."
That man is a criminal and a liar. he did not live up to the terms of the contract. He cheated you.
That is what the states have done to their workers.
2) If you bought a living room of furniture and deferred payment for a year, could you at the end of the year declare bankruptcy and keep the furniture? NO. The furniture store would come and take your furniture.
But that is what the states are doing to their workers. In this case, the Governor and the State did not set aside the pensions and are crying they still want the benefit of your work (the furniture) in their living room.
You would be called a liar and a cheat for trying this.
And in Wisconsin, not only does the Governor want to not pay the pensions but he wants to take away the rights of workers to set the terms of employment. He wants to take away bargaining rights won 100 years before.
