More on: we need better medicine

Medical care in the US has many, many deficiencies: care is fragmented; physicians are rewarded for "procedures" and tests, not for thinking; physicians are obsessed with billing, and distracted from real care; there's far too much overhead; medical records and care in general is badly under-automated; far too many people are excluded from the system; etc, etc.

That's not at all the same thing as "health care getting worse". Perhaps we're just becoming more and more acutely aware of what's possible, and how far we are from it.

Also, as frustratingly and tragically far as US healthcare is from what it ideally should be, it still appears to be as good or better than any other system in the world. Elsewhere, coverage is far more universal, but care is very badly rationed; research is a little less oriented toward big pharma (which is good), but fundamental drug research is mostly done in the US, and the US subsidizes the rest of the world by selling drugs at much lower prices than in the US.

The US has a larger % of people who are poor and without good health coverage than many countries, and therefore doesn't compare well. In that case, income distribution is indeed the key thing. OTOH, infant mortality in the US is decreasing, and adult longevity is increasing.
