It is very much not to support health in any way whatsoever. In fact the industry loves ill-health, because it's far more profitable than wellness.
Public not-for-profit health systems change that motivation into something that actually makes sense from a healthcare pov instead of just being an exercise in piratical opportunism.
Profiting from suffering without the slightest hint of altruism or empathy is simply sociopathic.
ACA's medical loss ratio provisions basically makes this impossible: https://www.cms.gov/marketplace/private-health-insurance/med...
That's not to say they're not incentivized to deny claims. If you are loose with what you pay out, you could lose money by paying out more than you take in.
I feel frustrated when it seems that so much money somehow is going to preventive care… But when they quantify it, it’s just looks like screening. They ask if I feel safe at home they ask if I want to attend a group weight loss class, when I’m 95 pounds. They, the gatekeeping front desk clerks or nurses, just screen screen screen and check off items on a checklist earning them loads of credit. All that screening results in an approved amount of preventative treatment.
How I love socialized medicine!
Preventative is very narrowly defined to exclude anything considered a sickness in anyway.
Getting something done that will ensure you don't get more sick might be considered preventative naively but is considered fixing a problem and so not covered.
So basically this covers vaccines (make sure if you get multiple you don't see a doctor past the first or you are paying) tests unrelated to medical problems and a single non diagnostic visit to the doctor per year.
