I think a UBI could work if all the money was generated through an increase in capital gains taxes on transactions greater than a million. currently the upper range of capital gains is 20% which is absurd considering thats where all the billions of dollars are being held. Makes no sense to give 1400 stimulus checks to a population being taxed like 20-40% of their income, just cut all the taxes for the middle class if they actually cared to do something useful..
