Kahn and Horowitz, along with Norman Hill, helped Bayard Rustin with the civil rights movement. Rustin had helped to spread pacificism and non-violence to leaders of the civil rights movement, like Martin Luther King Jr. Rustin's circle and A. Philip Randolph organized the 1963 March on Washington, where King delivered his "I Have a Dream" speech. King began to speak of the need for fundamental changes in the political and economic life of the nation and more frequently expressed his opposition to the war and his desire to see a redistribution of resources to correct racial and economic injustice. As such, he started his Poor People's Campaign in 1968 as an effort to gain economic justice for poor people in the United States. He guarded his language in public to avoid being linked to communism by his enemies, but in private he sometimes spoke of his support for democratic socialism. In a 1952 letter to Coretta Scott, he said: "I imagine you already know that I am much more socialistic in my economic theory than capitalistic". In one speech, he stated that "something is wrong with capitalism" and claimed that "here must be a better distribution of wealth, and maybe America must move toward a democratic socialism".
