This is literally our system:
When you're healthy, you get for-profit health care through your job. If you become infirm and cannot work, usually through age, but for whatever reason, you get expensive health care through the state after you have bankrupted yourself.
The entire premise of health insurance is having healthy people pay for the sick people to spread out the risk. But our system is "private insurance takes all the profits and the government takes all the costs".
And people wonder why things aren't working out.
It's too simplistic to blame this on government regulation. The rest of the world also regulates utilities, and far from all of it has the crumbling water infrastructure problem.
I'm not blaming the fact that government regulates utilities. I'm pointing out that using government regulation to simply drive prices lower is bad in the long term. Government regulation can work when prices are set at levels that balance investor incentives and consumer welfare. Doing that is really hard.
When the U.K. privatized British Telecom, it created a regulated monopoly (now BT Openreach) that owned the wires into peoples' houses. They spent a lot of time and intellectual energy into determining how to set BT Openreach's rates. As a result, that monopoly is more profitable than say AT&T (even including AT&T's lucrative wireless division). Unsurprisingly, BT Openreach has aggressively built out FTTN in the U.K. whereas U.S. telephone providers have been trying to limit investment in their networks.
Of course, you can say "who cares if Medicare drives prices too low, the drug companies will just have to deal with it." But in the long term, that's bad for the customer. All around the country you can see regulated rates that are too low and drive out investment. A great example is water utilities. Almost everywhere, water rates are far lower than they should be, and as a result water infrastructure is crumbling, customers are drinking water through lead pipes that haven't been replaced in a century, etc.
