Universal basic income is just communism 2.0. It's adapted for the sensitivities of the American middle and upper classes, who want to help the poor but only by giving money to make the problem go away.
Fundamental premise of UBI is everything is justly the property of the state. The state determines who should get what. Throw in a little capitalism and a little "I want to keep my upper-middle class life" and you get UBI. Everyone gets something, but those who make more get to keep some of that.
UBI in practice would likely lead to massive exploitation of the poor.
