Most healthcare systems in the US are non-profits. To run a non-profit, you still need revenue to operate no matter where you are or what you do. They have to pay their own bills just like anyone else.
Bring on the downvotes. Then go ahead and take all of your local hospital’s funding and see what happens.
Edit: maybe people misunderstood my point? People are replying and saying that profit shouldn’t be part of healthcare. Yes, but that doesn’t solve the problem of funding. Every hospital gets money. Pick your favorite country, the hospital still gets money.
