The slain civil rights leader was a critic of capitalism and the Vietnam War, and a champion of reproductive rights.

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.
