When President Lyndon B. Johnson launched the War on Poverty in 1964, his audacious goal was to end poverty in the richest country in the world by our bicentennial in 1976. Four years later, assassins killed two of the most powerful voices of this movement, and with them, our nation’s commitment to ending poverty.

This year, we commemorate the 50th anniversary of the deaths of Dr. Martin Luther King Jr. and Sen. Robert F. Kennedy. It’s worth remembering what both leaders were advocating for when they were struck down.

Dr. King had launched a “Poor People’s Campaign” as the next stage of the civil rights movement. It was this strategy, focused on changing the material conditions of poverty for Americans of all races, that led him right here to Memphis to support striking sanitation workers fighting for a living wage.

Sen. Kennedy was also focused on the plight of poor people. As he campaigned for president in 1968, he vowed to tackle hunger, poverty and racial injustice. Just two months and two days after the murder of MLK, RFK was assassinated the night after winning the California Democratic presidential primary on an anti-poverty platform.

Both leaders were deeply engaged in the moral challenge of ending poverty in America. Dr. King’s “outside” strategy used disciplined protest and disruption to force the issue of poverty on the national agenda. Sen. Kennedy’s “inside” strategy used a presidential campaign to force the issue of poverty on the national agenda.

Fifty years later, poverty and inequality are still an unconscionable aspect of American society. On the anniversary of the loss of these leaders, it’s worth asking the question Bobby Kennedy put to the country in a speech the night of Dr. King’s assassination: “In this difficult day, in this difficult time for the United States, it is perhaps well to ask what kind of a nation we are and what direction we want to move in.”

In 1968, the Kerner Commission — convened by President Johnson to understand the causes of urban poverty and inequality — released a dire report. It found that institutional and systemic racism were responsible for many of the ills that beset black America. It highlighted segregated housing, unequal public schools, and aggressive communities of color as just a few of the problems driving this crisis. The nation, the report famously warned, was “moving toward two societies, one black, one white — separate and unequal.”

A report released earlier this year re-examined the state of racial and economic inequality 50 years after the original Kerner Commission report. The new report found that in the past 50 years, poverty has increased, and the inequality gap between white America and Americans of color has either remained the same or, in some cases, increased. Just last month, social scientists released a study showing more evidence that black Americans still experience dramatically lower upward mobility compared to whites. It seems the Kerner Commission’s prediction of two unequal societies is closer than ever to coming true.

Fifty years later, we are still pushing for poverty-ending solutions advanced by both Dr. King and Sen. Kennedy. Proposals for guaranteed jobs and guaranteed income are back in the news and political discourse, as is a new Poor People’s Campaign, and not a moment too soon.

Community Change (CCC) was founded in the wake of the assassinations of MLK and RFK in 1968. As we celebrate our own 50th anniversary, we are committed to continuing to ask what kind of nation we want to be, and with the fierce urgency of now, continuing to push to end poverty in America.
