Eliminate certificates of need. Many states require you to prove need if you want to build a new hospital. You have to show that your new hospital won't reduce patients from an existing hospital. Capitalism works to reduce costs through competition. Need-based hospitals eliminates competition, allowing them to control the price of service. There's a pro-market solution. Outright ban for-profit hospitals. You can't shop prices or pick an in-network hospital when you're dying. Hell, you can't really even shop prices when you're not dying. So hospitals should not aim to make a profit because it essentially allows them to charge whatever they want; and you have little/no choice in the matter.

Neither of these options are perfect solutions. There's already a shortage of healthcare professionals and more hospitals will thin them out further. Profit isn't always greed. You wouldn't call it greed to save money in a bank for a rainy day, house, car, etc. Hospitals need to have some cash on hand for all sorts of things that come up. But even just *reducing* both is a huge start.

The issue is that these new hospitals are often built using state funds. You can't expect the state to subsidize your new construction without asking the question if you really need the thing you ask them to spend money on.
