Somewhat counterintuitively, often broadening access to healthcare, and reigning in prices ends up reducing the amount of money spent on healthcare, and I suspect its because when people go to GPs earlier, they end up heading off more expensive diseases later. If you catch a prostate cancer early, its *relatively* cheap to intervene. if you catch it late, it can cost hundreds of thousands. Likewise catching and heading off type 2 diabetes before it becomes diabolical and preventing it via dietry interventions is vastly cheaper than dealing with it when its a full blown crises. Warning signals for Emphysema can be picked up years before it becomes the dread disease it does when it fully kicks in, and can be treated with various interventions.
Coupled with keeping people in the taxpayers pool for longer , it just ends up with a reduced taxpayer burden and personal health cost burden.
The US spends ridiculously large sums on healthcare and ends up with a system thats internationally notirous for leaving vast swathes of people unable to access healthcare until its really too late. By contrast euro UHC countries end up spending much less.
An interesting case study is US vs Cuban health outcomes. The Cubans are dramatically poorer people than the US, and its health care spend is around half, vs GDP,, meaning the US spends around 4 x more per person on healthcare. And yet the Cuban healthcare system, for all the countries poverty is widely considered world class and life expectancies sit squarely in the middle of averages for first world countries, rather than the much lower rates found in other developing countries. Its kind of the countries point of pride, and tthey like to show it off by exporting doctors (The cubans train a LOT of doctors and use the surplus for foreign aid)
It seems paradoxical, but the secret is the Cubans focus on preventative medicine. Doctors will visit houses on rounds regularly , and do health checkups on pretty much everyone , annually (its compulsary) for healthy folks, and more regularly for folks with condition or elderly folks. That way they catch developing issues early and put people on programs to head off diseases before they manifest into much more costlier conditions to manage.
Now, I'm not suggesting the mandatory regular checkup sort of stuff the cubans do. Obviously that wouldn't fly in the US. But a UHC or UHC adjacent system with a focus on preventative medicine and regular checkups would absolutely reduce the burden of health costs. Like, for all his insanity RFKs concept of getting everyone in the US to eat healthy is not a terrible idea at all. Its the bizzare implementation thats the problem. But an actual scientific approach to health recomendations, coupled with some interventions to making sure poorer folks actually have access to good foods, and spending on community health centers to make sure poor folks are able to get regular checkups, I suspect it would go a long way to in reducing the sort of money the US is spending on health care.
