The legislation extending federal support for semiconductor manufacturing through 2030 is being debated in some quarters as if it were a special favor to a narrow industry. I would respectfully suggest that the framing is incomplete.

The household analogy — that the federal government, like a thrifty citizen, should refrain from spending when it is in debt — has a moral simplicity that conceals an economic confusion. The macroeconomy is not a scaled-up household. When private investment in a strategic productive capacity is insufficient, for reasons that include the long payback periods of fabrication facilities and the asymmetric risk borne by the first mover, the state has both the capacity and the duty to act.

I observe, further, that the political economy of the legislation has been improved by the conditions attached: clawback on offshored capacity, workforce pipelines that reach domestic workers, transparent accounting of which firms have received how much. These are not, as some have argued, departures from market principle. They are the institutional framework within which public investment becomes a complement to, rather than a substitute for, private decision.

The proper concern is not whether the spending should occur but whether the appropriations will be reliable across a change of administration. Strategic industrial capacity is not built on the rhythm of the appropriations cycle. The public faith required to attract the long-term private commitment is, ultimately, the question on which the entire enterprise rests.
