This is spot on. It’s not that I think health insurance companies are making insane profit margins. It’s that their very existence in the system is a pure negative and in fact a moral blight. Inflicting profit into a system that is entirely dedicated to human health is by definition a conflict of interest for basically everyone involved, even if it operated at a hypothetical 100% efficiency.
I don’t think health insurance is actually insurance, but I have seen little evidence that it has “insane profit margins”. From what I’ve read, ‘health insurance’ has middling profit margins relative to other insurance specialties; where are you getting that view/data?
Lots of things necessary for life are run by for-profit businesses — for example, food production. Do farmers have a “conflict of interest”? What about healthcare in particular makes profit immoral?
