Yes, this is the absurd part of the fat-hate movement, "you're wasting my insurance/tax dollars!" actually no fat people tend to die early, and US healthcare spending is absurdly weighted towards end-of-life care for terminal patients, something like 50-70% of your total life spending comes in the last 18 months of your life. Someone quietly dying at 50 of heart disease is really cheap compared to the person spending 10 years fighting lung cancer at 70.

Not that it should really matter, if the goal is to "get them healthy", right? But it's not, it's about having someone to hate and look down on. Black Mirror nailed this vibe perfectly in Ten Million Merits.

Anyway this is a specific problem with the US healthcare system though - we spend way too much on patients who are circling the drain and everyone else gets screwed. Broken bones and bad dentistry and missed immunizations are what produces the single largest improvement in health outcomes - Cuba really only has something like a 7-year reduced lifespan vs the US iirc, because they do well at delivering that basic care even if you're not going there for proton radiotherapy or other ultra-high-end treatments. And the US does the latter but sucks at the former.
