(1) Pension decisions play out potentially over ~30-40 years.
(2) If we accept that the cause is some official made a bad decision, it is almost certain that pension issues will be ongoing. There is potentially a 40 year window for idiots to get in and screw the whole system up.
So in a sense, some large group of people need to be responsible. Not because it is fair, but because if that isn't how we treat the situation it isn't likely to get fixed for the next round of pension crises. The pensioners were most invested in the success of the enterprise. They are most responsible for its failure.
This isn't a nice position to hold, but the alternatives are a very nebulous concepts of blame and lumping the cost of fixing all the mistakes on the one group of people who we know weren't responsible - people who are currently entering or in the workforce and can pay taxes.
Just phase them out and switch to 401ks. It’s absurd that such a large portion of government budgets are retirement accounts.
The unwinding is the terribly difficult part because the can keeps getting kicked down the road due to a combination of greed and incompetence. You need back pressure from financial markets to inhibit borrowing for what can never be paid back. Then the hard conversations are forced.
You simply stop giving new workers pensions, and you offer buyouts to the existing workers. None of this is fast, nor did I say it was. Even if you did it today, we're talking probably at least another 50 years before the last pension is paid out. Meanwhile, You're still dealing with the problems of running a pension plan, but at least you're on a path to divest from them.
This strategy is basically what every old company with pensions is doing. The problem here, is that governments don't do it, in large part due to the unions. I don't blame the unions for insisting on pensions, they're a good deal if you've got one But the fact is they're unsustainable. Unlike a company, the government is never going to go out of business, it's just going to become a retirement plan with a police force.
I think people are leaving Chicago over solvency/funding outlook issues. I have two barely wealthy (single digit millions, almost surely) friends in Chicago who are moving to Arizona and Texas because they worry they're among the juiciest targets to be squeezed in the upcoming years.
