Consider these facts:
• A significant majority of Americans are medically satisfied with their health insurance provider.
This should not be surprising because a large majority of Americans have only ever used their health insurance for things routine checkups, routine lab tests, common infectious illnesses like colds and flus, minor burns and cuts and other physical injuries, routine diabetes care, routine high blood pressure care, and vaccinations.
Those are all things where almost all of the time any insurance company will cover without any hassle or pushback.
• Older people are generally more likely to have medical problems beyond the kind described above, medical problems where insurance companies do start pushing back on coverage and treatments.
• The older you get the more likely that becomes.
What I'd expect then is that sentiment in favor of killing insurance company officers over the medical decisions of that insurance company to be higher in older people and lower in younger people. But it appears that reality is opposite of that.
