Your $1000/hr bill is really covering 5 other indigent hospital patients who can't financially cover the care the hospital is legally required to give. Rather than design a medical system that works for everyone no matter their finances we'd rather stick it to the middle class (the rich go to very different hospitals) since they have the most to lose and are the weakest to negotiate.
My roommate's bill for my own 5 day, $24k hospital stay was $0. My after-insurance cost was $2k, though I negotiated that down to $800 that I was able to pay off over a year (grad student on a stipend). Initially I was a little bitter about my roommate getting a freebie due to lack of insurance, but I eventually learned some compassion. In his case, he was unemployed and couldn't work due to a back injury.
So, we end up in this situation where those who have insurance subsidize those who don't. Many people who are ok with this are very much against an identical arrangement where the government is involved.
Yes, in my city there is a trauma 1, a few trauma 3s, and multiple hospitals who have no ER at all. T1 is downtown, surrounded by homeless encampments, and is perpetually broke. By city charter T1 cannot file for bankruptcy protection and cannot turn away anyone seeking emergency treatment. T3 and outpatient hospitals are in rich suburbs, no homeless camps, and the parking lot is full of luxury cars. They also cannot do most emergency services and will send you to T1.
The overnight stay in the T1 is $10k for a grimey room while the T3s are closer to $3k-5k before insurance. I've volunteered at both types and it is night and day difference in the staff and the patients.
Also, socialism.
