The US is the only modern country without cost controls. Providers set prices and insurance companies do little other than pass those costs onto consumers.
When will we get cost controls? Likely never. It's very anti-capitalism to restrain free trade. (Yes, there's some sarcasm there. This issue pisses me off.)
Until we treat healthcare like we treat our regional monopolies (electricity, education, etc.) the the government won't be able to set prices lower.
This is what we need in the US. I should not pay a different price if I have insurance or pay cash. People that pay cash are routinely charged far more than people with insurance.
Secondly, hospitals charge people with insurance more. Typically if a patient is uninsured and paying cash, the hospital will work out ways to charge them less, because they are personally liable for way more than what insured are. Hospitals still want to get paid, and charging a patient into bankruptcy is not a way to achieve that.
Haha fat chance. But there is the subsidy.
