Here's a good overview of Universal Basic Income:
One striking thing about guaranteeing a basic income is that it’s always had support both on the left and on the right—albeit for different reasons. Martin Luther King embraced the idea, but so did the right-wing economist Milton Friedman, while the Nixon Administration even tried to get a basic-income guarantee through Congress. These days, among younger thinkers on the left, the U.B.I. is seen as a means to ending poverty, combatting rising inequality, and liberating workers from the burden of crappy jobs. For thinkers on the right, the U.B.I. seems like a simpler, and more libertarian, alternative to the thicket of anti-poverty and social-welfare programs.
