I'm not sure this is so. Presumably this is offset by tax increases- which means no new money is injected into the system. Instead, it's a literal redistribution lf existing money.

While there might be some inflation as the supply of money available to those with low- to median income increase spending, I don't think it would be sufficient to offset the base change.

On the other hand you would need to significantly increase taxes on upper-middle+ brackets to ensure no new money is introduced. After all they receive BI under this system too, which they'd effectively have to pay back and then some....

Well UBI would naturally have to come along with greatly increased taxes on higher income levels, and property taxes would remain. I think the biggest issue of UBI is the transition period. How do you switch over?

The salary cut is also problematic. If you create a maximum wage that is too low you'd have employers competing for a smaller pool workers without any way to incentivize them. I suspect a great many jobs would simply become impossible to fill (oil worker, trash truck driver, construction laborer, etc). Perhaps you can make the amount say one million annually (adjusted to the now inflated dollars) but that likely wouldn't curb inflation all that much as few people are paid that well and would destroy the very tax base that is intended to fund the basic income in the first place.

I'd support a move to a "Star Trek" economy but I just don't see how you pull it off.
