Nah, they're one in the same... It is the hospitals that are charging $200 for an aspirin, etc. The insurance is happy to support the highway robbery, so costs can increase on the consumer side... Left hand, Right hand they are.
Actually, having been in practice as a speech and language pathologist in a rehab center setting for some time, I have to disagree.
There are problems on both sides, on that we can absolutely agree. That being said, insurance is the side that, quite literally, controls the entire medical sphere in the United States. One of the reasons I am no longer a practicing SLP is that I could not deal with insurance clerks being the ones making clinical decisions, and always that were not in the best interests of the patient.
Also, and this is really sad, too, it's because of how insurance has perverted things with "in network discounting" that some of the $200 aspirin has come to be. If you charge 25 cents for an aspirin (which is still way above cost), you'll very often not get paid a single penny for it. If you charge $200 the insurance company knocks off $199 and actually pays through $1.
But what's most outrageous is that if you are unfortunate enough not to have insurance, you have no legal recourse when you're charge $200 for that aspirin. When I was a teenager (which was a long, long time ago) and was a volunteer at my local hospital, we occasionally had different professionals come in and give talks. To this day I will never forget one local doctor saying, "Whatever you do, always have medical insurance, even if it's terrible medical insurance, because the hospital still has to discount to whatever they'd be willing to pay even if it's you paying the whole thing out of pocket as part of your deductible. Otherwise, you're able to be billed whatever the provider wants to charge."
Health care in the USA has been screwed up for many decades, and its "compounding factors" constantly at play in a private, for-profit system that escalate the rate of insanity. And, if anyone thinks non-profit hospitals don't make a profit, well . . .
