There is almost no criticism of Physicians in all of this. They are a top 4 lobbying group with a half a billion dollars in bribes. They use their private, unelected group ACGME to reduce supply of workers... and on-topic: the billing of insurance maximum rates seems wrong.
Yes things get 'adjusted', but it creates a culture where you cannot pay out of pocket and there is no competition for reduced rates.
I don't even mean to pick on Physicians here. If you look at the top lobbyists, pharma, pharmacists, pharmacies, insurance companies, and hospitals all make top 10.
I cannot see the path to reform, there is too much non-partisan money here. The electorate is divided on solutions, so there is little appetite by serious politicians to make this a major campaign plan.
Maybe there are historical examples of how to reform. Tragedy?
