For some of them, I was able to sign them up for Medicaid, so their stay could be covered. Lots of people set up payment plans. For the people who didn’t/couldn’t pay, we would send them to collections. My hospital very, very rarely wrote anyone off. IIRC the cost for one night without insurance was around $4k.
I was raised as a strict Catholic, then stopped believing once I went to college and met people who challenged my worldview. Now I am agnostic. Not sure I want to call myself a definitive atheist, as I believe there COULD be something out there. However, if there is something out there, I don’t think it cares enough about this tiny blue dot in the entire universe.
