Of course it's the government's responsibility. It's impractical as a grass roots effort. What happens when multiple citizens accidentally engage with the same CEO? Sounds messy and awkward.
It seems like it could be simpler to exercise government to enforce fair standards and health care access.
Of course, I shouldn't jump to the conclusion that the remaining living healthcare CEOs will choose to cooperate with the due process of law, rather than live slightly more egregiously hedonisticly in fear for their lives.
