Since the pensions are one of the biggest financial issues, there is one easy reform that would save a lot of money.
The workers like to fight every attempt at pension reform with the argument that they have paid "their fair share" into their pension (which is debatable). Well, the one thing that isn't debatable is that the workers have made their contributions as a % of whatever salary they were making at the time while currently their pension payout is paid based on their highest salaries.
If a teacher gets hired at 40,000 and retires at 90,000, and was paid an average salary of 70,000 during their working career, their pension should be based on 70,000, not 90,000. That is how their contributions came into the fund and that is what would be fair to them and the taxpayers.
