When profit motives “are considered more important than people,” Dr. Martin Luther King Jr. once declared, it’s time for the nation to “undergo a radical revolution of values.”

To bring about that revolution, King and other leaders announced plans in December 1967 for a Poor People’s Campaign that would mobilize disadvantaged people across racial and geographic lines. Four months later, an assassin’s bullet prevented the campaign from reaching its full potential.

Today, 50 years later, we have a chance for a do-over. And do we ever need it.
