They don't? Most ?! Most argue that if the governement could use it's position to negotiate prices that ressemble the rest of the world... If that were the case you still got a lot of money to waste before paying more for the same service.
Read back, then; it's been argued multiple times in this actual thread. Any time I suggested that prices for care would drop, meaning that doctors and nurses get less money per unit of work, leading to labor movement out of the healthcare sector as it becomes less rewarding, I was told that this was ridiculous. Meanwhile, repeated reference has been made to the scurrilous health insurance companies rationing care and refusing to pay as much as the government would.
Of course, when it comes to negotiating prices in line with the rest of the world... well, multiple analyses including the
OECD find that US healthcare prices are already in line with the rest of the world and right on trend, and that US healthcare spending is greater because the US
buys more healthcare than any other country. Insurance companies already negotiate prices well below sticker, by the way.
Not to mention, if you have ongoing prescriptions for pills, your private insurance can just decide to no longer cover your pills at any point in time. Then you pay the full, several hundred dollar price. Those pills you need to live or something.
So can the government; or if it can't, then the government coverage is less efficient than the private coverage because
other people, taxpayers, are being forced to pay for the pills when the insurance company decided they weren't worth the money. Insurance doesn't generate money from nowhere - with private insurance, it comes from premiums, while with government coverage it comes from taxes. So in both cases, someone's paying for it, and if it isn't worth the price for one, it isn't worth the price for the other.
By the way, health insurance companies are
already regulated so they can't just drop coverage for life-saving medications, so this example actually doesn't matter in the first place.
