And Dr. Quentin Young, whose patients included Dr. Martin Luther King Jr. and a young Barack Obama, has died at the age of 92. Young was one of the nation’s leading advocates for single-payer healthcare. Speaking on Democracy Now! in 2009, as President Obama laid out his plans for what would become known as Obamacare, Dr. Quentin Young criticized his former patient and longtime friend, saying Obama’s plan didn’t go far enough.

Dr. Quentin Young: “The problem is the diagnosis here. America’s difficulties, indeed the crisis in healthcare, is due to one big thing: the multi-payer and private insurance companies. Everybody knows that. Obama knows that. He said he was for single payer not that many years ago, and if he was starting from scratch, was the way he put it, he would go with it. Well, he is starting from scratch, and the failure to grasp the nettle and really give America the kind of healthcare reform system it deserves is very painful and very dangerous.”

Dr. Quentin Young died Monday at his daughter’s home in Berkeley, California. He was 92.
