Many year ago I lost my job and just as I got a new job but before my insurance could kick in, my appendix ruptured. I had to get surgery and was in the hospital for 3 days, the bill came to something like $25,000.

I negotiated with the hospital, they reduced it to $11,000 and set me on a payment plan. After I paid off the $11,000 they sent me to collections for the other $14,000. Those fuckers.

I refused to pay it and it tanked my credit rating, which made it difficult to get a home loan five years after.

Well if we say the doctor was getting paid a very generous $300 an hour for that work, that's $450.
Plus seeing the front desk person for a few minutes, we'll give a generous $50.
So that's $500 for some very well paid employees.
We'll throw another very generous $50 in for the antibiotics, making it $550.
Double it so the hospital can take a very large cut, and your total is $1100.

So even leaving massive profit margins with those numbers, you still got ripped off an extra ~$5000.
