There is nothing quite like a Libertarian fanatic; reason flees, questions are not answered, reality is avoided etc.
Prices have been set for centuries. Have you ever heard of a "Contract of Adhesion?"
Was the drug purchased for $13 under a contract of adhesion? Or is that simply another strawman?
You assume I am a libertarian. That is incorrect.
I cannot see any rational basis for your insistence that the owner of an item cannot set the price for that item. The contract of adhesion you allude to in this instance is nothing more than socialist price controls to be set by the federal government. Government control is not the answer here.
