The problem isn’t the funding it’s people’s reactions. Why slave away for someone else’s company even if it provides utility for your society if you can survive and even thrive creatively on UBI? What happens then, do we get worse class warefare then we have now? What happens when people realize most of what can be automated away at current levels are executive and CEO positions? When they leave with Golden parachutes are you gonna ask for UBI for them? No then we have set a precedent legally for those automated away jobs to not receive UBI or you just facilitated more capitalistic greed for those executives. Is UBI setup on a global scale? No then how do you enforce dual citizenship individuals from collecting UBI and working another job remotely from the second nation they are registered with creating inefficiencies in our program with could make it a target for regressive policies. Think Republicans constantly saying illegals are stealing our benefits so we should block them and cut funding to the programs, how do we defend against those attacks? I mean I can keep going, but the problem is how do we implement this without everything being automated and create a fair and equitable system for all involved? While it would be nice to just throw money at everyone you need to take into account individuals reactions to this. We aren’t in a vacuum and yet we isolate ourselves in echo chambers as if our perspectives are the only ones out there, we loose nuance by doing this and then get aggravated something isn’t done because the cause of that nuance isn’t even on our radar from lacking communication with other people who have differing views and opinions.
