Every January, Martin Luther King, Jr. is universally honored as a national hero who preached a peaceful fight against racial injustice. This saintly image is quite a departure from the kind of attacks the reverend endured over his lifetime. FBI Director J. Edgar Hoover famously called King “the most dangerous Negro” and “the most notorious liar in the country” while keeping him under close surveillance. Over the years, Dr. King’s more controversial edges have been smoothed over, burying his more radical teachings.

1. He pushed for a government-guaranteed right to a job. In the years before his assassination, King re-shifted his focus on economic justice in northern cities as well as the South. He launched the Poor People’s Campaign and put forth an economic and social bill of rights that espoused “a national responsibility to provide work for all.” King advocated for a jobs guarantee, which would require the government to provide jobs to anyone who could not find one and end unemployment. The bill of rights also included “the right of every citizen to a minimum income” and “the right to an adequate education.”

2. He was a critic of capitalism and materialism. King was a strident critic of capitalism and materialistic society, and urged Americans to “move toward a democratic socialism.” Referring to the now iconic Greensboro Lunch Counter sit-ins, he asked, “What good is having the right to sit at a lunch counter if you can’t afford to buy a hamburger?”

King also explicitly linked the problem of capitalism with the problem of racism. “When machines and computers, profit motives and property rights are considered more important than people, the giant triplets of racism, materialism and militarism are incapable of being conquered,” he argued in a speech at Riverside Church in 1967. The reverend was very aware that this kind of challenge was even more dangerous than his work on segregation and civil rights. “You can’t talk about solving the economic problem of the Negro without talking about billions of dollars. You can’t talk about ending the slums without first saying profit must be taken out of slums,” he warned his staff in 1966. “You’re really tampering and getting on dangerous ground because you are messing with folk then. You are messing with captains of industry. Now this means that we are treading in difficult water, because it really means that we are saying that something is wrong with capitalism.”

3. He denounced the Vietnam War. King’s harsh words on the Vietnam War alienated even his allies on civil rights, especially President Lyndon B. Johnson. Still, King continued to speak out, asserting that American involvement in Vietnam “has torn up the Geneva Accord” and “strengthened the military-industrial complex.” He also accused the U.S. of being “the greatest purveyor of violence in the world.” Not only was the Vietnam War morally unforgivable in King’s eyes, but it also took away billions of dollars that could be used to help end poverty in American slums. “Our national priorities are disastrously confused when we spend more than $30 billion a year upon a tragic, destructive war in Southeast Asia and cut back on the programs which deal with the most basic injustices of America itself,” he wrote.

4. He championed Planned Parenthood and reproductive rights. King believed that the spread of family planning was a crucial tool in the fight to end poverty and racial inequality. “I have always been deeply interested in and sympathetic with the total work of the Planned Parenthood Federation,” he said in 1960. He connected reproductive justice with racial justice, noting that the impoverished African American community had “a special and urgent concern” in family planning. Because of these views, he believed access to contraception and family planning programs should be funded by the government.
