Earlier quoted context omitted.
They've chosen 90% margin (cost + 1000%). Semicon tool builders (my industry) have margins around 50% (cost + 100%). This is considered high margin manufacturing work. To match United Health's margins we'd need to raise prices by 5x.
I agree, but we can't talk about "over" without talking about where the line is.
One part "free market -- maximize your profits as much as you can and get rewarded by a skyrocketing share price!"
And one part, unspoken except in the PR BS put out by the insurance companies, "Try to improve the health of patients and have them not die!"
The only way the two can coexist at all is if someone draws some lines like you are suggesting. I know that there are some (probably easily manipulated) laws stating that X% of premiums have to be "spent on care" and if they get too high overall margins on your group, they have to give your employer a rebate. Of course, who knows whether you'll see that money.
If we just say "maximize your profits" (and indeed, shareholders 'should' sue them if they don't) then it's obvious that morally bankrupt scum that runs all these insurers would 100% extort people for 1000% profits on lifesaving drugs. It's the most logical course of action! People will pay infinity dollars to save their own lives/their loved ones, so let's soak them!
If it's not obvious, I believe that overall the "free market" part of this system is a failed experiment that should be abolished immediately, and not just because I want all of these companies' sickening, greedy executives to go straight to hell (where Brian Thompson is burning today).
