Kevin Drum. You can see that employment for coal miners fell by 100,000 between 1950 and 1955, before there were any environmental regulations to speak of. Trump supporters are claiming that his waving off a single proposed environmental rule will save 70,000 jobs, but there are only 65,000 coal miners in America. Incidentally those 65,000 miners produce 80% more coal than the 400,000 did in 1950.
This chart is just for miners, and there are plenty of other people who work in the coal industry, but miners are the largest category and the overall numbers have followed a similar trend.
It seems strange to me that we are so focused on coal these days, given that even by a broad definition that includes power plant workers there are only 175,000 jobs in the whole American coal industry, 0.12% of total employment. Why not give a little attention to waiters or nurses?
