Conditional welfare programs require administration and monitoring in order to ensure that funds are distributed only to people who qualify. This can sometimes result in the need for elaborate (and expensive) testing and monitoring systems.
A variety of different UBI schemes are possible, from using UBI to replace all existing benefit programs to introducing UBI alongside existing benefit programs as a complementary form of assistance. UBI could also be funded in a number of different ways, such as a flat income tax or a more nuanced tax on undesirable socioeconomic outcomes such as pollution or extreme wealth. Regardless of the specific implementation chosen, the administrative overhead normally associated with social programs is minimized for UBI because UBI does not require means testing for eligibility; everyone is eligible by definition, and everyone receives the same amount of funding.
Implementation of UBI is ultimately dependent on the financial viability of the program, and UBI is not financially viable in any form that would have a significant impact.
Conditional social welfare programs are more difficult to implement because they require testing for eligibility. UBI is unconditional; it does not require means testing.
The difficulty of implementing a social welfare program is not solely determined by the need to assess eligibility.
