The PBGC report misses much of what has been happening among defined benefit plans.
Carrying a very different cost structure than your competitors and having an element of unpredictability relative to competitors has caused many companies to move away from defined benefit plans.
I am an extraordinary fan of defined benefit plans, but the world has in fact dramatically changed. If the offset is that companies start aggressively encouraging people to save and provide financial literacy education, that may be a very positive silver lining.
