However this saves us from inflation, since the money circulates among the wealthy and corporations rather than among the common person.
That's why printing cash (whether in the form of UBI or any other cash printing social program) is not a sustainable solution for lifting people out of poverty or building a healthy economy. There are always negative long term effects that end up hurting the poor and middle classes even more. Even if there's not inflation of consumer goods, there's inflation of investment grade assets.
