Purdue Pharma is a recent instructive case. The marketing folks did some terrible stuff, but it would be pretty rough on victims, employees, and patients who need pain meds to respond by tearing down Purdue's factories and auctioning off the contents. So the bankruptcy plan calls for keeping the factories running, transferring them to a new company called Knoa, which will be owned by a trust that's dedicated to managing the opioid crisis. Isn't Knoa just Purdue wearing a new hat? Kinda, sure, but there's no better alternative.
Easy solution: fire (and imprison) the executives, sell off the entire company, leave the owners/investors with nothing.
That sets a proper incentive for shareholders to not send yes-men or people with a dozen or more other well-paid low-effort board memberships into corporate boards but people actually willing and capable of controlling the executive.
(As, perhaps, they should be.)
It used to be that "company reputation" was part of the value of a stock certificate. That disappeared and the primary value of CEO became being a sufficiently raging asshole to pump the value of the lottery ticket at all costs.
Bringing back a bit of risk to investors would help put some pushback into the system.
