The capital stock framing is right, but the mechanism goes one layer deeper. We didn't just move production offshore — we moved the process knowledge that ran it. Capital can fund new structures and machines. It can't compress the institutional memory that accumulates in tooling, process engineers, and supplier relationships over decades. TSMC Arizona is the proof: unlimited capital, world-class engineering, still three-plus years to high-volume production. That ceiling is the constraint the investment charts can't show.

The machinery line is the one to sit with: construction spend more than doubled since 2022 and still lands at 3.9 billion, which shows how thin the base is. The deeper gap is that the machines that make the machines sit abroad. China now produces roughly a third of the world's machine tools and just passed Germany as the largest exporter. A funded reshoring push still routes its deepest tool layer through foreign suppliers, which is the part a CHIPS-style subsidy doesn't reach.
