Governments and medicine tend to track deaths as the only bad outcome from events like 9/11 or Covid. But typically there are a lot more people injured who suffer for the rest of their lives with the consequences, damage and chronic conditions that these events have left them with. We do need to put a lot more research into understanding and improving the quality of life of those with chronic conditions, Historically they have been ignored and are currently highly stigmatised by governments, the press and the populace.
Diseases that lead to death have had substantially better funding over the past 100s of years and chronic conditions are often rarely diagnosed, properly recognised let alone treated. The disabled is a club almost everyone joins at some point in there life and everyone is one accident or infection away from joining it for the the rest of their life. At the moment societies recognition and treatment of those with these conditions is really bad. The 9/11 survivors will be suffering for the rest of their lives. Medicine is something we all want, but at the moment the amount invested by governments is quite low compared to the upside impact on humanity of finding real answers.
I totally agree with you, it is important for people to understand that a medical doctor does not really care if you can walk a mile without pain, but it is way too nuanced to track quality of life changes across a large population. We would need to change the insurance landscape and make it easier for other medical practitioners to get insurance money and let it naturally change.
If even a little bit of the insurance money could start funneling into things like physical therapy (actual physical therapy not the BS artists at big hospitals who print you out a sheet of generic exercises) people could see practitioners who actually care about you being functional.
I tore my achilles and saw a string of doctors, podiatrists, physical therapists, chiropractors, etc. before finally finding someone that doesn't take insurance but who had me running again within a few months. He was cheap compared to the amount my insurance was being billed for a chiropractor to try and sell me $500 custom insoles. The money is there it is just being funneled in all the wrong ways.
