Why Doesn’t American Healthcare Help Us Live Longer?

The answer appears to correlate quite well with one’s income. On average, the better off you are, the longer you live. By extraordinarily large margins.

And if the House/Trump bill to repeal Obamacare becomes law, we have to expect this to worsen.

From Kevin Drum:

The difference in life expectancy between the top and bottom is ten years for women and a stunning 15 years for men. Nor do you need to look at the very top to match European life expectancies. A merely average American has a life expectancy of 82 years, right in line with other advanced countries.

So here’s the question: I assume that every country shows a decline in life expectancy as you get poorer. But do other countries show the astonishing decline we have in the US? I can’t find an authoritative analysis of this, but I scanned through some reports from different countries and it looks to me like the income difference in most places is half to two-thirds of the US difference.
