Part of the problem stems from a generous corporate bankrupcy law, which I understand lets companies "restructuring" include everything from outstanding debt to labor contracts and pension obligations. Once those costs are "controlled", the comapany can emerge from bankrupcy -- which seems fair enough, but which then gives them a competitive advantage over companies which havent been released from previous obligations.
That in turn pushes the previously healthy companies into price wars that they cant win, and thence into.... bankrupcy.
And each time the cycle gets run, the giovernment becomes the payor of last resort for pensions, and once again the taxpayers at large foot the bill. WE pay for the competitive cycle, on April 15th instead of at the cash register.
