BI as a supplement to wages and other resources already exists in the form of welfare and the like, its just a matter of reducing the conditions to nothing.
somebody mentioned 600 a month for BI, you could do something lower without needing to quadruple tax revenue
From the calculations above, that requires 5050*267 million more government revenue than we have, or 1.35 trillion dollars (after cutting the non-old age part of Social Security, and the welfare part).
How are you going to raise that 1.35 trillion dollars?
Also at 600 a month, we arguably cannot drop minimum wage.
My conclusion does match my statement (that BI is generally a bad idea, and wouldn't cause significant decreases in other social programs).
As far as the rest of your comment, by reducing the conditions to nothing, you dramatically expand the expenditures while lowering the tax base by encouraging a portion of the population to not bother being productive. People like to say that welfare acts as a form of BI, but that is far from the truth. Most welfare programs in the US contain requirements that recipients at least look for a job, stay drug-free, etc. With BI, people that don't want to work will simply move in with each other. $12K/yr isn't really enough for 1 person to have a good life; however $60K/yr for a household of 5 with no taxes taken out comes alot closer.
