Why is US healthcare so expensive?
Seven structural drivers compound: layered middlemen (the top 3 PBMs control 79% of Rx claims), administrative overhead (34% of spending vs 17% in Canada), brand drug prices (2.78–4.22× the OECD median), hospital consolidation, defensive medicine ($60–80B/yr), price opacity (only 34.5% of hospitals comply with transparency rules), and employer-tied insurance. None of them is 'individual choice.'
