This doesn't seem to even try to explain by what measure 401(k)'s have failed (if the problem is low contributions, that is not the fault of the 401(k)), or back up the suggestion that pensions are not bankrupting municipalities.
It seems to mostly invoke the Koch brothers and paint a target on The Investor Class, and hope that is proof enough.
If the Koch brothers favor pension reform, then by definition pensions are not failing!
(I'm sure it is for some)
