Expecting voting to fix democratic capitalism is as ridiculous as expecting workers’ councils to fix vanguard communism.

Quite possibly, but AFAIK it's the main lever, along with voting with one's money. I'm certainly not proposing that democratic capitalism works in the long run, and yet there's no question that with a more educated base that truly wanted to maintain democracy, various nations could have done a better job staving off late-stage capitalistic collapse.
