How about this:My edited post addressed that somewhat....
"It's just a proposal for a simple system that's
analogous to single payer free health care.
For high income earners, much of it would
be recouped by taxation, thus reducing their
benefit automatically."
To your post, sure, the UBI could phase out
as income rises. I could live with that.
Instead of giving them money, give them health insurance, food, shelter, but only give it to those who can't afford it. Higher income and middle income who don't need anything don't get anything. Do you have a problem with that?
