Your example is leagues of laws and regulation on top of a scam, a pyramid model that affords top care for those who can afford modest premiums and really do get expensive care for $5 copay, at the cost of everybody else who has to fight their employer via federal politics for the right to go bankrupt.
Indeed, I would say that using insurance to pay your insulin bill is coming out on top of the scam, because some books are getting cooked (+/- paper costs) at the expense of mutual indemnity (taxes, social security). An insulin user is a health insurance voter, but that is a weak expediency for actually fixing the price of insulin and ending the tyranny of insurance companies over healthcare, and it turns whole populations into do-or-die partisans.
Thanks, Obama!
