Where do benefit corporations and b corps (https://www.bcorporation.net/what-are-b-corps) miss the mark?

Benefit corps have the specific purpose to increase prosperity for all stakeholders - not just shareholders. They are indeed a proposal for a "new operating system" for companies, and it is adopted by many companies (some very well-known) already.

The basic idea is to put a statement of public benefit in corporate bylaws, then sign up for an assessment that audits that your company actions are indeed aligned with public benefit.

This effort, nominally, would seem to address many of the problems laid out in the post, but benefit corps are not mentioned once. I'm not saying its _the_ answer, but seems like a more collaborative, concrete starting point for a solution than "some mass infusion of the 1960s spirit."
