It's largely a side effect of a couple things... first the ACA (ObamaCare) limited the percentage of profit that insurance and medical providers can make... so they instead just grow the pie larger by inflating everything. Second is that they are allowed to have effectively vertical monopoly investments controlling multiple layers of healthcare as a whole from insurance, providers, pharma and pharmacies.
Trust busting and multiple supply lines really need to be established in order to have a chance at restoring normalcy. Which is all but impossible as Pharma alone is the single biggest spender of advertising alone, let alone policy influence over politicians.
How exactly do they make more money by not paying? They're required to spend 80% of their funds on provider expenses. The only obvious way to sustain the narrative that insurers are distorting the system for profit is the preceding comment's hypo that they'd be over-paying (and then driving rates up as their expenses increased). You propose the opposite fact pattern here.
(Net cost of health insurance, all expenses, is around 6.5% of total US spending, as against 51.5% of direct provider costs for doctors, nurses, and procedures, not counting prescriptions.)
