Like every other business in America? Are you really that thick?
Now go Google the Sherman, Clayton and Robinson-Patman Acts and ask why are medical health providers and medical insurance provided not prosecuted.
Add NEW requirements (and implement the bureaucracy to enforce them) OR reduce regulation and enable free markets to operate and get government out of the way. But try to do both, and you set yourself up for failure. By the way, point number 2 from your original post would obviate the need for requiring point number 1. In a free market, providers would communicate prices and consumers would act accordingly. There is no need to mandate the requirement.
