Why should the majority of people settle for the leftover scraps of the capitalist class? I do see that it is possible for UBI to exist within a system where the means of production is under public ownership and democratic control, which I believe is necessary for social justice. However, if UBI is ever implemented in a fundamentally capitalist society, it only means that the wealth disparity has grown so large that the capitalists, in the act of preserving their heads on their necks, allow for a crappy standard of living for the rest. Although I could see myself welcoming UBI for a multitude of reasons, I am also scared that it would entail some form of permanent class disparity with the majority of people forever impoverished.
