I don't think we definitively need single payer, but we do need uniform (per provider) pricing and price transparency. (Although allowing everyone to buy into medicare/medicaid would be a no-brainer)
Barring systematic reform, I'd really like to see a trend of "healthcare extortion trusts" to keep everyone's life savings safe from these vampires.
And I want to add to this: patients can't even be held at fault for this: have no ability to even find out! I've asked and asked for this up front (after being hit myself with a huge bill for what was a tiny visit! No surgery, just an examination!), and been told by providers that it is "impossible" to provide even an estimate of a price, even when the provider has all of my insurance information. Which is bullshit.
To make a patient choose between an unknown bill and their health is extortion.
How is that corruption? Who is being corrupted, and by whom? The state cannot corrupt itself.
Obviously if you define the term "corruption" so that it is inapplicable, then there is no "corruption". FWIW I'm totally on board with viewing "the state" as a singular malevolent actor, I just don't think that paradigm is particularly useful here.
