Health insurance profits are capped by government. They aren’t immensely profitable in the strictest sense of the word. That’s why they had to refund premiums during COVID.
That seems immense to me.
From an emotional perspective sure. Their revenue is more than 1 trillion, so while less than 4% lower prices would be nice it wouldn't really fundamentally change anything.
You mean costs can be inflated? Yes, the American healthcare system is extremely inefficient but that doesn't help the shareholders of those insurance companies at all.
