Perhaps I should revise. Forecasting costs given a smaller finite set of parameters is possible. Private companies do indeed seem to do it well. Much better then the public entities. Especially when healthcare is involved.

Yes so one statement out of all the other points I made was arguable. All of the other ones do indicate that the way that it is being done now does not work and costs the taxpayers alot of money. Furthermore that the amount that is being heaped on the taxpayers could grow dramatically based on the outcome of future court cases as more municipalities fall by the wayside and look for ways to keep those pension checks rolling.
