In 1968, King and the SCLC organized the "Poor People's Campaign" to address issues of economic justice. King traveled the country to assemble "a multiracial army of the poor" that would march on Washington to engage in nonviolent civil disobedience at the Capitol until Congress created an "economic bill of rights" for poor Americans.
The campaign was preceded by King's final book, Where Do We Go from Here: Chaos or Community? which laid out his view of how to address social issues and poverty. King quoted from Henry George and George's book, Progress and Poverty, particularly in support of a guaranteed basic income. The campaign culminated in a march on Washington, D.C., demanding economic aid to the poorest communities of the United States.
King and the SCLC called on the government to invest in rebuilding America's cities. He felt that Congress had shown "hostility to the poor" by spending "military funds with alacrity and generosity." He contrasted this with the situation faced by poor Americans, claiming that Congress had merely provided "poverty funds with miserliness." His vision was for change that was more revolutionary than mere reform: he cited systematic flaws of "racism, poverty, militarism and materialism", and argued that "reconstruction of society itself is the real issue to be faced."
The Poor People's Campaign was controversial even within the civil rights movement. Rustin resigned from the march, stating that the goals of the campaign were too broad, that its demands were unrealizable, and that he thought that these campaigns would accelerate the backlash and repression on the poor and the black.
