Here is my perspective on the answer to your question:

Our government is not functional. It is not that it doesn’t “want” a healthy work force, but that it isn’t capable of setting any sort of a policy.

The last time the US made any meaningful change in healthcare policy was under Obama. My impression of what happened is that there was a brief (2 yr) moment when the Presidency, House, and Senate were all controlled by the same party. The Democrats passed “health reform” which was basically the Republican health care reform package from 4 years earlier.

In the 13 years since then, the only Republican position on health care has been that Obama’s “ACA” law is “bad”. There is literally no suggestion of what else would be better. (I’m not counting the anti-abortion laws as “health care” – they are seen here as a moral issue, not a health care one.) The Democrats’ position has been a mix of “we shouldn’t let the Republicans take us back to something WORSE!” and “the whole system is broken and needs to be replaced”.

We have two problems. First, our government is structured so that it cannot easily accomplish anything, at least without cooperation between the two opposed parties. Secondly, one of the two parties is insane and wants to destroy the government (and has enough electoral support to win almost half the time).
