People hate it when faceless bureaucrats decide that some health care expense is too expensive for the large faceless bureaucracy to cover, when they have a medical issue that they would like the large faceless bureaucracy to spend money on. Perhaps in that world, some insane guy with a back injury who's unhappy about the quality of his care assassinates the Secretary of Health and Human Services, rather than the CEO of a medical insurance corporation (and hey, a lot of people hate RFK Jr. anyway, so maybe that assassin still becomes a folk hero for doing it).
