It doesn't make much sense to give, say, $700 to millionaires who don't need it (and then tax back part of it). Even the "Economic Impact Payments" given for COVID had an income level cutoff (too high in my view), and nonetheless it cost $814 billion. A Brookings Institution study found "payments would be better targeted if aimed at households who have lost income or who are in danger of losing income". A minimum income approach is preferable to a Universal BI.
