A couple of Krugmans

Paul Krugman has two posts of interest up:

*  one about worries about private debt in China.

* the other is about increases in life expectancy in the US being not all that it seems.  I assume he won't object to my reproducing it in full:

I was pleased to see this article by Annie Lowrey documenting the growing disparity in life expectancy between the haves and the have-nots. It’s kind of frustrating, however, that this is apparently coming as news not just to many readers but to many policymakers and pundits. Many of us have been trying for years to get this point across — to point out that when people call for raising the Social Security and Medicare ages, they’re basically saying that janitors must keep working because corporate lawyers are living longer. Yet it never seems to sink in.

Maybe this article will change that. But my guess is that in a week or two we will once again hear a supposed wise man saying that we need to raise the retirement age to 67 because of higher life expectancy, unaware that (a) life expectancy hasn’t risen much for half of workers (b) we’ve already raised the retirement age to 67.

I wonder whether the Australian increase in life expectancy is more evenly spread across income levels.   Given our system of health care, you would certainly expect so.   (But of course there is a big disparity between aboriginal and non aboriginal life expectancies, even though I don't think that is something that is relevant to the Krugman argument.)
