Unfortunately the only true path to universal basic income is to make income obsolete. As long as we continue to use a monetary system there will never be basic equality let alone a sustainable way to provide income. I have no idea what we would replace it with, but instead of working towards universal basic income we should be working on universal basic human rights with rules set in place that require any leaders who break these rules to be severely punished. Remove the glamor of power completely. These rules would also apply to individuals. Good luck with that.
