Good and realistic, with caveats. would need to replace other social programs, removing admin costs, and it would need to be structured as a negative income tax, where it slowly phases out as you earn more, and it needs to be out of control of congress. (monetary policy domain)
Honestly depends on how it’s implemented. I am for it. But it dose have some unseen side effects. Like what happens to drug addicts who now have a bunch more cash? The government now funds their addiction.
