New money derives its value, subtractively, from the value of existing money (“WEALTH”), which is held by individuals who earned that money (“WORKERS“).
Some individuals decide not to work because of reasons OTHER THAN retirement, inheritance, disability, and child bearing; these individuals do not contribute directly to production (for convenience, we’ll call this group “LAZYS”).
Therefore, giving UBI to LAZYS intrinsically takes WEALTH from WORKERS, regardless of whether not WORKERS also get UBI.
In other words, universal basic income can be correctly defined as “transfer payments from WORKERS to LAZYS“.
