But those increasing prices for robot labor are (partially) fed into the basic income, so UBI receivers will have more to spend. There is a cycle and how quickly it cycles will be determined by how quick the various parts move. Not all robot owners will increase their prices just as fast and people will not buy from the overtly expensive sellers. Similar to the economic cycle we already have. I certainly don't have an economics degree though.
