No worse than "Trump matters" tee-shirts.

Understand why Donald Trump is so popular: middle-aged white men without college educations are dying in record numbers, and they’re killing themselves. 

Something startling is happening to middle-aged white Americans. Unlike every other age group, unlike every other racial and ethnic group, unlike their counterparts in other rich countries, death rates in this group have been rising, not falling.

The mortality rate for whites 45 to 54 years old with no more than a high school education increased by 134 deaths per 100,000 people from 1999 to 2014.

“It is difficult to find modern settings with survival losses of this magnitude,” wrote two Dartmouth economists, Ellen Meara and Jonathan S. Skinner, in a commentary to the Deaton-Case analysis to be published in Proceedings of the National Academy of Sciences.

Dr. Deaton had but one parallel. “Only H.I.V./AIDS in contemporary times has done anything like this."

Ignorance is a slow killer.
