> 1) they're poor and have no money
I had a kidney stone several years ago. I suspected, but didn't know, and the pain was crippling (vomiting, crying in the fetal position).
I went to the ER. CT. They loaded me up with pain killers and moved me by ambulance to another hospital 15 minutes away because they had no urologist available. They took me to theater, found some infection, abandoned plans, IV antibiotics, discharged me the next morning, to return 2 weeks later for lithotripsy or otherwise.
So I came in with a kidney stone, left with a kidney stone (and stent, and pain management).
My bill for this 12 hour process was between $60-70K.
"They're poor" doesn't cut it.
This is a very common thing. And while my presentation was less common, it's still not unusual.
You're not poor if you can't afford a $70,000 unexpected bill for an ER admission, a CT, an abandoned surgical procedure and a stent and an overnight bed on a ward.
> 2) medical debts are easier to ignore than other debts that these people also have (because they're poor)
"ignore" is doing some heavy lifting. There's an element of that, sure, but remember: these had to be legislated to not affect your credit score because they're almost always events that were not poor judgment on your part, but unplanned (they're not being generated from elective or cosmetic events). And people were being penalized for having the unmitigated gall of not having, to use my example, $70K laying around, "just in case" they got sick. And those penalties have real impacts. You still need a roof over your head if you're sick, but good luck finding a rental, let alone a mortgage, with that on your credit report.
