I have seen the meme of the "death of the defined benefits pension is responsible for <societal ill related to retirement/wages>" but it doesn't make any sense to me upon reflection. It isn't like defined benefits plans created stable returns via magical pixie dust. There would still be pressures and systemic consequences from the failures. The pension model essentially assumes either a far slower world or a protected relatively stagnant market. Even with "shift to government run pension" as a concept still has the same sorts of pressures no matter who the can is kicked down towards.
