In other countries there are private health funds that return all of their profits to their members by simply covering more types of care and lowering premiums, all while still giving their staff very good, very attractive pay. That is clearly a win:win setting without being a government-run entity.
A person doesn't need to earn 100M-200M in a decade of company service. That is an obscene amount of money, and merely opportunistic payment from a system where the foxes are guarding the hen house. Unfortunately the US health system has this pattern repeated through it from insurers, to hospitals and beyond - the money is being funnel to those which can minimise, not optimise, care.
