Yes, but once you give everybody $X,000 dollars per month you'll spur inflation and in a couple years $X,000 will no longer be enough to live on. So then you've got to adjust your basic income to $(X+Y),000 per month to make sure everybody has enough, but that will spur more inflation and you'll be right back where you started. Meanwhile, that money has to come from somewhere and it will come out in the form of taxes. Remember, that only about one in three people in the US is employed. So now every working American has to be taxed enough to pay for three basic incomes plus their own incomes on top of that. The rich will complain about the added taxes, but it's the middle-class that really suffers, since they will NOT escape the added tax burden and their extra taxes combined with rising inflation mean they now make just barely enough to get by, effectively placing them in the lower-class. Now you've got a gigantic lower-class, a tiny middle class, and an upper class that only gets richer because they can accelerate the rate at which they siphon off income from the lower classes through price increases.
It's a nice idea, but it's not a good idea.
