yep, that's only one of the many political hurdles that ubi needs to overcome.
You think that all of those administrators would just let their little kingdoms be thrown into the dustbin? Not likely. You'd be laying off an army of government workers that now ironically would have to survive on ubi. It's political suicide.
Look, I'm actually in favor of many of the ideas around ubi, but again, you will never see it happen in your lifetime.
