UBI would raise inflation so essentials would cost more defeating the objective.
Instead of paying (using us money) 50c for a can of beans you`ll be paying $3, instead of $1000 rent you`ll be paying $5000. It would also wipe out your savings & any pension funds earned & payed out.
This is basic ecconomics give everyone a $1 million dollars and you`ll all be having to pay $1 billion a year in rent like back in the Weimar Republic. Nobody gets richer quite the reverse.
So bad idea
