I would contend that everyone/society benefits from having the population, as a whole, being healthy.

More people who are able to be productive members of the workforce, better mental health from improved financial security, and less cost from preventative rather than responsive treatment.

That also gets to the heart of the problem - not everyone recognizes the benefits that I've suggested from a more universal healthcare system.

I would also contend, that I don't see the benefits from the level of military spending that we have.
