Negative Income Tax is pretty much the only implementation of UBI I personally could get behind. I just wouldn't be able to support an implementation of a UBI that pays Bill Gates the same amount as a person born with a severe disability (which obviously they had no choice about being born with).
The system for everyone should be the same. It's simpler and more fair. Bill Gates deserves to know that if he lost it all tomorrow we would take care of him. We can make one system that ensures everyone is cared for. The sickly and the ambitious. I don't think we have the proficiency necessary to keep people from falling through the cracks otherwise. Maybe in very specific cases (like Bill Gates) but not at scale. There are disabilities that exist that we don't even know about yet.
Unless taxation and reporting are made trivial (which is hard without giving up on privacy including cash), the poorest do not have the money or time to jump through hoops. Hence UBI, having the minimal requirements, will help the most of the poorest. This more than compensates for the (arguable, but I'll concede it) bug of giving some money to the rich as well.
Well that is fucked up? They dont call it a "UNIVERSAL" basic income.
Yeah let's give a basic income to EVERYONE, EXCEPT ... that makes 0 sense. You just described wellfare really.
Universal or bust. Everyone or no-one imo. It's a universal basic income afterall. Not a conditional basic income.
If world governments continue to fail also at corporate tax, the current dystopic situation of regressive effective corporate tax rates through profit export will persist, and risks everything we have gained through capitalism and democracy.
I encourage you to read the definition of UBI. Universal means you give to everyone, from the homeless guy on the street, to Bill Gates. Not just laid off people. Also, your top-of-head speculations are not the best evidence available for its effects.
