UBI has always been a scheme developed by billionaires to lower the tax burden. Seriously, just look at any politician or think tank associated with it, and it will usually be funded by a billionaire.

UBI is meant to keep the status quo, or to even roll back social safety programs like Medicare, Medicaid, and social security. Billionaires would rather pay people a static couple a thousand bucks a month than pay for the inflating cost of healthcare, education, and affordable housing.

Almost all serious attempts to pass a UBI bill have been made as a response to things like Medicare for all, or to programs like rent freezing.
