Nah, we do a lot of good too. I mean if you were to rank all of our medical interventions on a spectrum of cost effectiveness, vaccines would probably take the cake but ozempic would do very well. On our side, we can all think of examples where radiation quite probably added 15 years to someone's life, or examples where an extra 10 fractions added just to a hospital's profit margins with no improved outcomes.
I think that same paper also said that curing heart disease would only add 4 years to average lifespan?
My broader point was that life expectancy, while maybe our best metric, is not the only thing. For better or worse, freedom to eat a burger and fries is one of those uniquely American freedoms, written not into the Constitution but into our societal DNA. There are conversations going on to control freedom of the press (e.g. clickbait social media and the networks that profit from them), freedom to bear arms, but no one is out there trying to rein in our freedom to order a burger and fries.
