Inflation would rise if UBI is paid with newly printed money and deficit (e.g. covid checks). If it's paid with taxes, nothing should change in terms of inflation. Surely, prices close to the consumption should rise, and price of capital goods should fall, but overall it stay the same.
We don't have a balanced budget. Programs like UBI would most likely not be paid by taxes (which would be better used for education/trade programs that I mentioned) but by increasing the deficit. There is no undo button. Millions of people would be dependent on it. You will have no choice but to print money.
I suspect California will try UBI anyways and fail spectacularly. It will be a canary in the coal mine.
Weird that you got downvotes by saying what's widely know in the field of UBI. Almost any UBI proposal includes the slash of all other programs.
The main strenght of the UBI is that it simplifies the bureaucracy: in theory, you just give everyone an income that should cover health insurance, education when needed, food, housing... so if anyone prefers to spend the money on drugs and hookers is up to him: the society already provided with everything he needed. The key is that you can live with the UBI, and if you want recreational drugs you have to find a job for the extra money or sacrifice some of the basics.
UBI + lots of other welfare programs makes little sense.
