Paul Krugman documents a concrete reallocation problem: massive capital spending on AI infrastructure is displacing investment dollars from housing construction and manufacturing, sectors that directly employ millions and build tangible assets. AI capex benefits a narrow set of tech companies and their shareholders while housing scarcity and industrial decline hollow out middle-class wealth-building pathways. The oligarchic effect emerges not from AI's capabilities but from how capital markets are rationing investment, creating winner-take-most dynamics in tech while productivity gains in other sectors stall.
