Additionally, the first thing you have to do when you go to the doctor in the US is sign that paper that basically says “I agree to be responsible for the bill, no matter what it ends up being.” Which is ridiculous given you can’t know what the bill is until after you’re charged.

Imagine going to the grocery store and there are no prices on anything. You load up your cart and walk out and the grocery store sends you a bill months later. The bill is enormous because the grocery store has a signed statement from you agreeing to pay whatever they want. That’s the system we have for healthcare.
