It wouldn't be "regulating" the price in the way you are suggesting.
It would be the Bureau of Consumer Protection actually doing it's job (which they don't in the case of healthcare costs).
When you go to the hospital they don't even give you an itemized bill unless you jump through a ton of hoops to get it. Which is how they price gouge you with ridiculous costs like a $50 paper dixie cup to drink a sip of water from when you take the $10 tylenol pill.
As for prescription drugs...the federal govt. not only looks the other way, but has given Big Pharma the right to charge citizens in the U.S. an exorbitant amount for medication. Even going so far as to use Federal authority to stop you and I from being able to cheaply get the same exact medication from other countries at less than half the price.
THAT is govt. interference and goes against a Libertarian view.
But it plays right into the hands of Republicans and Democrats who work with the huge lobbyists from Big Hospital Corp.'s, Big Pharma, and most of all Big Insurance.
I'm against it. And it seems to me that since the Democrat Party tries to make people think they are for the "common man" and against big EVIL corporations...I would think that most Democrats would be against it too.
But of course what the 2 ruling parties supposedly "Stand" for is nothing but an illusion they use to get votes and keep power.
