I wish someone would challenge the premise that a "basic income," a basic standard of life is something that can even be identified. I challenge the idea that people can point to some standard of living and say, "that is the basic standard of living that people, and we should provide people with that standard of living."
The problem is that Americans, and most societies in the West in general, have totally lost touch with basic human existence. For example, in New York right now, people are delivering pre-cooked, packaged food in single-use containers to poor people[0]. If you can't provide food for yourself, are we to assume that this is the standard level of living that you are entitled to? I wouldn't be surprised if many people say: "Yes, this is what people who can't provide for themselves need."
My opinion, however, is that sustaining people in this way is completely unsustainable, a form of terrorism on the environment. You can't just give people free endless takeout and say that that is the basic standard of living they need to advance in life. But that is how this is being done right now, because the people who think UBI makes sense, I find, are by and large the same people who consume prepared, plastic-packaged foods all the time. These people, largely, live unsustainable, intensely capitalism-based lifestyles, and think for some reason that it makes sense to bring the rest of the world into their divorced for nature-reality existence.
Giving people a "universal basic income" so they can live the destructive Western capitalist lifestyle is a plague on our species, human culture, and worst of all, on the environment.
