For many if not most of the affected imports, it would never ever make economical sense to try to rebuild a local industry from scratch, at least not without major subsidies. And as for local alternatives that already exist, they carry a premium higher than any tariff (because a local workforce likes to be paid living wages), even if magically scaled up to achieve some degree of economies of scale. Western economies are truly and irreversibly post-industrial.
