"There's a time bomb ticking in America's private pension system. Although the airline industry's hefty $32 billion in unfunded pensions has captured headlines in recent months, the problem extends much further. Automotive companies, for instance, have about $60 billion in pension shortfalls. The Pension Benefit Guaranty Corp. says U.S. pension underfunding at large companies grew 27% last year, to $354 billion. The deficit for all companies was a staggering $450 billion. Compare that with a total shortfall of less than $50 billion in 2000, and it's clear that this fast-growing crisis must be addressed while the PBGC -- already facing a $23 billion deficit after taking over terminated plans from the likes of Bethlehem Steel and United Airlines -- can still shoulder the burden."
so you can't say Unions are killing anyone- the pensions they negotiate aren't getting funded anyway.
