I believe there should be a government backed, credit union style, non profit operating in every industry as a baseline for companies to compete against.
I don’t think that would work. The big insurance companies would find a way to undermine that. But also, the government insurer would end up with the most expensive patients who can least afford premiums, and then the libertarian types will use that to show how the government isn’t as efficient as the private sector.
I have no idea what the actual solution should be, though.
