March for Jobs and Freedom

"Schooled at Crozer Theological Seminary in the teachings of the Protestant Social Gospel movement, King's theological vision included an economic critique. In a November 1956 sermon, King presented an imaginary letter from the apostle Paul to American Christians, which stated, 'Oh America, how often have you taken necessities from the masses to give luxuries to the classes... God never intended for one group of people to live in superfluous inordinate wealth, while others live in abject deadening poverty.'
"Unfortunately, since then, inequality has only grown. The Economic Policy Institute reports that, in 1962, a family unit in the top one percent of U.S. households had approximately 125 times the wealth of an average household. By 2004, it had risen to 190 times."
