Thomas Frank believes in populism with a capital P, and he says so in this 2020 The People, No: A Brief History of Anti-Populism. It relies heavily on Martin Luther King, Jr.’s All Labor Has Dignity; in turn, King’s Populism arrived from C. Vann Woodward’s 1955 The Strange Career of Jim Crow, as Frank points out in a footnote. He quotes from King’s speeches to labor unions that repeatedly assert, if labor goes down it will be because “the forces that are anti-Negro are anti-labor and vice versa.”
The Bourbons, King recounted on conclusion of the Selma march of 1965, “took the world and gave the poor white man Jim Crow.” Frank quotes King:
And when his wrinkled stomach cried out for the food that his empty pockets could not provide, he ate Jim Crow, a psychological bird that told him that, no matter how bad off he was, at least he was a white man, better than the black man. And he ate Jim Crow. (170)
