Things like cost controls and universal coverage are synergistic. People with coverage will seek earlier, cheaper remedies over waiting to the last minute expensive emergency care.
Republicans and conservative Democrats have allied to sabotage the ability for universal service to control cost. From the abandonment of the Public Option in the ACA marketplace, to disallowing Medicare Part D from negotiating with drug manufacturers for lower prices. We've been effectively hamstrung, but that means there's plenty of low-hanging fruit.
If the US got its obesity rate under control, we could save a lot of money (less hypertension, less diabetes).
I pay $6000+/year in health insurance in the US + deductibles + co-pays + + + and I don't even know if they'll cover me when shit really hits the fan - but hey, I'll get a flu shot "for free".
Check profit margins for companies in the health care space, they're pretty good.
As you can see, obesity is a leading risk for all these problems.
We need to fix obesity.
