However it is important to recall that the people who actually made all the money extracting the wealth got out years before, retiring and/or selling stock. They're bystanders now and probably happy to run the whole operation again.
Although as an aside who these people are who think corporate pensions are a good idea is beyond me. People really should be in charge of their own savings in preference to their employer, expecting some random corporation to cover the cost was always a bit crazy even when it seemed sort-of possible that the system was stable. It is easy to have some sympathy but, as a practical matter, it was never going to work and it isn't a surprise that it didn't.
Ignore the practicalities and look at the story.
They're a promise that someone stronger than you will provide for you in your old age.
