People frame it like that, but in practice it would be offset by increased taxes for most.
For example, everyone gets $20,000 per year as "universal" basic income. However, your taxes go up $20,000 per year or more because you weren't in the lowest tax bracket. We have to pay for the UBI somehow.
UBI of a substantial amount would be incredibly expensive. Expensive to the point that the taxes would have to dip all the way down into the middle class to make it work. So for the average person, that UBI would come in and then go right back out as taxes.
