Per the study we are discussing -- as well as the results from every single other developed country I believe? -- more efficient when it comes to healthcare, yes.
Because both studies and real-world results from every other developed country show gov is more efficient at healthcare, is your argument that means gov is more efficient in every field?
The perverse incentive of the politician / general / bureaucrat to favor their personal interest over the public interest is identical to the perverse incentive of the CEO to favor his personal interest over the same.
I would argue the government case is actually much worse because at least the CEO has the feedback mechanism of revenue because the company <> customer relationship is entirely voluntary on both sides. The public vote is supposed to restrain the government in the same way, but in practice it seems to be much less effective in restraining politicians than the customer is at restraining companies.
I can if I want to switch jobs too. Probably not a good idea given the current economic conditions. I'd be all for forcing a decoupling of these things, but I don't see that anywhere on the table, and it would probably run afoul of politics anyways.
