As Bayard Rustin put it in his address to the 1970 Convention of the Bricklayers, Masons, and Plasterers International Union....

“The fact is that if you are going to deal simultaneously with black rage and white fear, the only group in the nation which has the answer is the organized trade union movement because it says: ‘There must be full employment for all who want to work.’ If there was full employment, blacks would not be in a rage because they do not have jobs, and whites would not be fearful that they will lose theirs.”  Bayard Rustin, Black Rage, White Fear, Berkeley: University of California Press, 1970.
