Of course, there are objections to UBI, mainly revolving around how it would be paid for. However, since the financial crisis we know that governments really can create money out of “thin air” so in reality that argument is a non issue. UBI would perhaps lead to problematic inflation but the best guard against this would be to introduce it gradually. Additionally, government creation of money for UBI would be from a non debt source and thus banks’ money and credit creation could be more substantially controlled with much less effect on the economy, with the added advantage of less indebtedness to create the same amount of money overall.
We’ll just print the money and give it to everyone.
