“I have a friend, Big Bill Broonzy the great blues singer. And Big Bill and many elderly black men of a certain age were jacks of all trades. They were the grandsons of slaves and they could be masons and carpenters and electricians. Big Bill was a welder, and a very good one. And he taught this young white kid how to weld. The day the kid learned how to weld correctly is when they fired Bill. And he chuckles. Now why did he chuckle? It’s a safety valve.”
Why did he chuckle?
