maybe replacing everyone's defined-benefit pensions with 401(k)s and IRAs wasn't such a good idea
Also, what about the increased risk of corruption leading to underfunded DB pensions? Which is apparently near certain, given that pretty much every defined benefit pension fund across the US is underfunded.
Defined contribution plans didn’t spring out of the ether on their own. They were a reaction to evident rampant risks and deficiencies of defined benefit plans even after many failed attempts at reducing that risk via regulation.
