Earlier quoted context omitted.
You can't get treatment for life-threatening "conditions". You can only get treatment for life-threatening "emergencies". You got a tumor? Good fucking luck. You got a seizure because of your tumor? Come on in and we'll make sure to send you an absurd bill later.
I know multiple poor people that had their cancers cured without cost to themselves, no "emergency" required. The reality isn't as bleak as you are making it. The US has the highest cancer survival rate in the world, which would not be possible if poorer populations were not having their cancers proactively treated.
The US isn’t bad in that respect, but according to Wikipedia, this statement isn’t even true for the subset of countries on their list: https://en.m.wikipedia.org/wiki/List_of_countries_by_quality...
