I would like to point out that you have a very privileged position in life to be able to say that cost is no object to the quality of care you receive. Not every has that luxury. Also, there are some people in some situations that would be willing to sacrifice quality of care on price.
Don't belittle the point by calling it "privilege". I'm in the same situation as most Americans with employer-provided health insurance. The real cost decision, as I pointed out in another comment, is whether or not to get care at all, rather than to choose between Doctor A, or Doctor B who costs 5% less.
This is exacerbated by the fact that our insurance hides most of the cost variation from us anyway, and health care networks turn potentially cheaper care into probably much more expensive care. Writing this all off as "privilege" is a gross, lazy oversimplification.
