Sure, pension reform is absolutely necessary. The federal government recognized this in the 1980s and are still making adjustments to the current system to stay solvent well into this century (right now funded through 2075). Even the military system is undergoing changes now, so the only thing left is the Congressional retirement system. I'm sure they will quickly fix that soon enough.
States and municipalities are recognizing the issue, Rhode Island, South Carolina, Florida and others have made strides in fixing their shortfalls. Cities like Detroit were forced to because of bankruptcy, and that seems like the logical conclusion for the state of Illinois and Chicago.
I mean it's absolutely crazy that public employees are allowed to cross the 100% salary threshold and bring in 1.5X or more what they made when they worked. I mean that's 3rd grade arithmetic, sooner or later that system is going to crash and burn.
