The CEO is primarily responsible to [maximize profits for] shareholders, not necessarily to benefit patients. If shareholders wish for better care to be provided to patients, I’m sure they would be happy to accept a lower rate of return on their investment.
It's almost like profits shouldn't be part of the equation when we are talking about humans lives and health.
Noone should enrich themselves on others not getting the health care they need, and those who do it today are morally bankrupt -- and society should fight back.
Shareholders of publicly traded businesses have governance power; they can vote for or against board members and policy documents.
Perhaps this is one of the concerns with the rise of index funds— fewer investors make use of their governance power and the index funds just vote according to the recommendations of the current board.
