Earlier quoted context omitted.
the idea that you can get sick one time and be financially ruined is still astonishing to me. FWIW I'm not aware of many people who come down with a cold and are financially ruined. The people I know who are in crippling medical debt have, for example, had both kidneys replaced. While I'm not happy they are in those circumstances, it's not hard to picture two replacement kidneys and all the other treatments involved…
Still though (and correct me if I'm wrong), but if you get sick tomorrow with some ailment for which treatment is complex (and therefore expensive) AND you don't have insurance - your options are to find the money or go bankrupt? That's nuts in 2018 in a wealthy democracy.
Think about how cuba is able to have similar life expectancy, etc at a fraction of the cost with chronic shortages and subpar sanitation. Most likely there are many medical procedures doing at best nothing for the patient except draining their wallets.
Worse, it could be that treatment 1 for problem A causes problem B which leads to treatment 2, etc, etc for some moderate benefit at great cost over just dealing with problem A.
Worst, it could be the medical treatments are having a net negative effect on people's health. Eg, those studies that estimate hospital errors (not even just death from dangerous treatments applied as standard) are the third leading cause of death in the US.
