Earlier quoted context omitted.
I have a $6500 deductible. I definitely care what things cost because my insurance almost never actually helps pay for anything unless I have an unbelievably bad year. The problem is that literally nobody can tell me how much anything is going to cost until I get the bill in a month. Not even because they don't want to tell me. Nobody at the desk even knows what my price is going to be because it's all numberwang.
You care about small costs but not the large ones. Even with a relatively large deductible it’s irrelevant to you if your hospital charges $50k or $90k for a surgery. $6500 is nothing once surgery, radiation, and/or anesthesiology enters the picture.
But when you get into the really big, serious, time-sensitive things. Cancer treatment, heart disease, anything that starts with an ER visit... you don't really have an ability or time to "shop around". The demand is inelastic.
