Good question. I think they don't. I think they die. Or they mortgage their house and deplete their funds and then they die. Or they find charitable sources.
They probably can get on Medicaid once they are poor enough. But I believe Medicaid has some pretty strict limits on what they will pay for. And then they die.
That kind of thinking is what brought us Obamacare.
There was a woman in my town who came down with brain cancer. She had young children and the surgeons wouldn’t operate without being given $35,000 up front.
She tried fund raisers, there were money jars all over town, but in the end she could’t raise the funds...so she died, leaving young kids behind, orphans.
That kind of barbarity shouldn’t be in a nation as wealthy and compassionate as America.
