The economy has been more productive. Funds for pension maintenance were simply diverted to other purposes. Politicians signed agreements with unions and didn't follow through with their promises. I have yet to read solid evidence they couldn't have or that it would have been impossible if other decisions hadn't been made. No politician seems to care about what happens after their term is up, so they have no incentive to ensure the financial infrastructure is in place and remains healthy.
