Well, because it is perfectly intuitive to think it will cause inflation: The Fed printing money to fund Government deficit spending absolutely increases inflation. UBI is additional Government spending. Additionally, reducing the supply of labor increases the cost of labor, which causes inflation.
I think the onus is the proponents of UBI to somehow prove that if this is done at scale it will NOT cause inflation.
> On the plus side, the advancement of AI, and the threat of widespread job loss creates a positive talking point that can possibly help counteract that.
Academics have been making these doomsday "automation will cause labor surplus" predictions since forever. When exactly can we expect them to materialize? I'd love some cheaper labor so I can build an affordable home.
