The US healthcare system is well and truly f'd, but I think 98% of these issue are government and society policy issues. If anything, I see so many companies trying to take advantage of the complete dysfunction in the US healthcare system to be yet another middlemen siphoning money from systemwide inefficiencies.
My primary point is that poor health outcomes in the US (fully admit my views are US-centric given my experience and knowledge) have nothing to do with a lack of technology and everything to do with structural systems issues rooted in government policies.
I'm a big fan of Dr. Jessica Knurick, who publishes at length about many of the systems that cause and contribute to population-wide poor health in the US. Here's one article taking about food systems and nutrition: https://open.substack.com/pub/drjessicaknurick/p/the-food-sy... .
