“…For decades, people in rich countries have lived longer. But in a well-known paper, economists Angus Deaton and Anne Case found that over the past 15 years, one group — middle-age whites in the United States — constitutes an alarming trend. They are dying in increasing numbers. And things look much worse for those with just a high school diploma or less. There are concerns about the calculations, but even a leading critic of the paper has acknowledged that, however measured, “the change compared to other countries and groups is huge.”
