China has a third of global manufacturing capacity (and have to run flat out to avoid deflation due to domestic consumption that will never grow to meet domestic production capacity). Only the unsophisticated could believe the US is going to increase domestic manufacturing capacity at the levels needed to make domestic sourcing superior in some manner. That’s why these tariffs are not grounded in reality.
In three years at the most, these tariffs are done. Cheaper to eat the premium in the short term versus suboptimally invest capital in long duration investments (ie local factories and equipment to fill them). Manufacturing jobs continue to decline, as they have since the election.
