I do not like UnitedHealth, I do not like our existing crop of health insurance executives, and I might even be viscerally glad at some level that the UnitedHealth CEO was killed in a world where justice clearly takes a back seat to greed, but I wish the headline didn't say "overcharged", because there's no established amount of markup that is the correct amount of markup other than what people end up paying. Is that shitty? Yes. Does it violate a social contract? I think so. But tell me how much the right amount to charge is first. Is that cost? Cost+percentage? They've chosen their percentage. What's the correct one instead?
The article body presents the story in a more meaningful way, "UnitedHealth Group is charging patients a markup for key life-saving drugs that could easily exceed their cost by a factor of ten or more".
