Or regulate prices. How can a hospital charge $250 for an IV bag while in Europe the same bag is 10€

Or an ambulance ride in the US STARTS at $500. An ambulance ride in the EU is 260€/hour (obviously is free in case of emergency)

I think the problem is that the US is in this weird dynamic in which hospitals charge more because "the patient is not paying for it, the insurance is" but in the end insurance are going to raise premiums to pay for that
