Michael Harrington was a writer and scholar primarily concerned with the problem of poverty within the otherwise affluent postwar 20th Century USA. He grew up in a Midwestern Irish-American family, and he attended parochial schools, where he excelled academically. Harrington moved to New York & became involved in the Catholic Worker movement, before he lost his faith and turned to more secular political organizations. He considered himself a socialist, but he downplayed those beliefs when he wrote a bestselling book aimed at liberal reformers entitled "The Other America: Poverty in the United States." That 1962 work became a bestseller that helped to inspire Pres. Lyndon Johnson's Great Society programs. Harrington continued to speak out against economic inequality throughout his life. He founded Democratic Socialists of America (DSA) during the 1980s and remained its leader until his 1989 death from esophageal cancer at age 61. During the 21st Century, DSA experienced a boom in membership, but it also began taking controversial positions that some original members questioned. We conclude the episode by noting that Harrington's work exposing the neglected issue of American poverty remains relevant today, as the USA's unusual gap between relatively high average incomes & relatively low life expectancy continues to grow.
