Yes, the GDP for the US in 2020 was ~21T and 15T is quite large in perspective. However, this UBI would generate tax income to offset. In fact, its been stated that welfare like food stamps (SNAP) actually brings in more 170% revenue vs. assistance provided [1]. If this is tax revenue positive (even if the return isn't as high as food stamps), why would the cost be a concern?
