Hospitals have incentives to have a high sticker price - it benefits everyone. The insurance companies negotiate to something closer to the "real" price. That makes them happy. Government through Medicaid/Medicare has a way of giving money to hospitals. Customers only care about the out of pocket cost - indeed if they happen to notice the sticker price it'll only be after they know what they're actually paying - so that will actually make them happy.

There's a very small group. 5% or so of people, those who don't have private insurance and aren't on the public insurances - edicare/Medicaid/VA - . Those people are actually in a position where they get to see the sticker price but might have to actually pay it.

Which sucks.

But I don't see how that changes. The people getting abused are - despite what you might hear - are small in number, typically healthy and not particularly poor or old. The ACA actually went after those people - that was what the mandate was about - and tried to get them to buy a lot of insurance. More insurance then they wanted - and the end result was that the mandate's been effectively gotten rid of.
