I'm skeptical of these UBI experiments in general, because they don't take into account that widespread, permanent UBI will change people's behaviour in very different ways from a small, temporary experiment. How do populations respond when they are guaranteed $2k / month forever no matter what they do? Do they simply start asking for $3k / month after that? Does the median individual stop working and watch TV all day, or do they do amazing creative things?<p>One crazy experiment we could try: Give Finland (they've run a small-scale UBI exp before) $1.2 trillion to run a nationwide, long-term UBI experiment on their whole population(5M (pop. Finland) * $24k / year (UBI payments) * 10 years = $1.2 trillion).<p>Make the decision about UBI based on what happens in Finland after 10 years. Not perfect, and it will never happen, but certainly would be a more trustworthy indicator of UBIs real effects on a society :)
