alt Hacker Newswell inflation is equivalent to a flat wealth tax that doesn't consider insoluble assets, and is entirely in the hands of the government that imposes the UBI.
"cause increased prices for consumer/essential goods" is what you meant (since buying power is moved to people who are reliant on buying them), but this is a one-time transition to a new equilibrium (so is mitigable by increasing the UBI to account for it), not a constant ever-looming devaluator.
True, but again, the other points are more damning.
We're talking about an increased federal budget in the hundreds of billions/trillions to support such a UBI. That will cause a massive increase in taxation on the people who can still find jobs.
To make matters worst, the government in 10-15 years will likely be spending ~25% of it's budget on interest payments alone. Hiking the federal budget up even more sounds like a hard sell.
