I think the only way that UBI would work is if the educational system is radically overhauled. If the point of education now is for citizens to exist and work in a industrial / technological service economy, then all learning is focused on that. In a system without this financial construct, education needs to be about self actualization and self motivation. What if at the very beginning of our schooling, we were taught how to be the best versions of ourselves and contributors to our societies based on something other than commerce. Currently we are molded into constructs that are more about commodification of everything rather than values based on human potential.
