The scary truth is that the prescribing doctor probably prescribed what they thought would best treat their patient's condition, and access to that medication requires hundreds of dollars because the manufacturer can simply charge that much, so why not? Your insurer denied you, again, because they can, so why not? Manufacturers give coupons that bring down the cost of their medications by hundreds, even thousands of dollars, so they have something to point to when they're accused of profiteering and exploitation. Your life and the lives of your family members depend on this system not fucking any of you over for a buck, despite fucking you over for a buck every step of the way.
