Not even countries that have a tax base above 80% can finance a basic income at this point.  A general reform of global economics would be needed...not likely due to the destructive greed that seems to be on the rise. Our president and his guppies are the best example. Our own grant system is being bled dry by billions in corruption and mean business models and the rest of the SOEs that would go a long way to alleviate poverty are all personal bank machines for the "ruling class".
Before we don't fix that plus increase our tax base, you solution is not possible I am afraid.
