This might be the saddest song ever written — and as we approach Labor Day next week, a stark reminder of why the labor movement was (and is) necessary. The first time I heard this was at a Woody Guthrie anniversary concert at the Brady Theater in Tulsa a few years ago. It made me mad then. It makes me mad now. If it doesn’t make you mad, I have serious questions about whether you could pass Philip K. Dick’s empathy test.
