We always suspected this: a new study clearly shows that the richer you are, the longer you live in the US of America (Wall Street Journal). This is no small difference! The top 10% (richest) people live on average 10 years longer than the bottom 10% (poorest). Wow! And this is WITH medicare and medicaid, which the political right would have us get rid of all together.
What I would like to see are 2 things.
(1) A comparison with a similar study in civilized “1st world” countries (Canada, UK, Germany, France, Switzerland, Netherlands, etc.) with better health care coverage that covers the entire population.
(2) A historical comparison: an analysis of life expectancy relative to individual wealth 100 , 50, 20 and 10 years ago in the US. I would like to know whether we have made any progress, and whether (as I suspect) progress has been halted or even reversed.
It will take at least 10-50 years for the effects of Obamacare to show up in such a population wide analysis which measures death rates over many years. At present, only a comparison with other countries can tell us something.
Here is a partial response to my question (2) from the article itself which looks at least at 2 different historical time points: 1920 versus 1940. For men there has been an improvement in longevity (5.9% for the richest men and 1.7% for the poorest men). For women the change in longevity is 3.1% for the richest women. But the poorest women actually live less long -2.1%. This means that if you are a poor woman, you actually would have been better off being born in 1920 rather than in 1940! That is a stunning fact. It is the reverse of progress.
