From what I know, some capitalists support UBI because it would serve as something of a palliative for declining demand caused by automation and the resulting decline in profits. It would seem, however, that as automation proceeds, there would need to be an increasing tax burden upon capitalists in order to raise money for the UBI, which would approach 100% as we proceed towards full or near full automation, which would of course mean the end of capitalism. Thus, ceteris paribus, UBI doesn't actually solve the contradictions of capitalism.
