Several points worth noting here:
1) The incidence of the tariffs is mostly being paid by US consumers. For example, the tariffs on aluminum and steel have allowed these industries to expand and increase employment. However, the cost of steel has risen dramatically. For each job saved in the steel and aluminum industry consumers and businesses have paid an additional $900,000 through higher prices -- more than 13 times the wage of a steelworker. (Peterson Institute)
2) The net effect on jobs in the US economy from higher tariffs is zero. Tariffs can save jobs in the steel or aluminum industry but it drives up prices in steel-using industries. The higher costs imply higher prices for these goods and less demand. If the demand for products falls and then so does employment. A dispassionate look at the data shows no (positive) correlation between tariffs and aggregate employment nor a (negative) correlation imports and employment.
3) A 25% tariffs on autos and auto parts would be a nightmare for the US auto producers and US consumers. Global supply chains would be seriously disrupted and the impact on costs would likely exceed the implied tariff costs. In fact, the uncertainty about tariff policies and a trade war seems to be having a negative impact in several markets.
4) Using tariffs as a mechanism to get concessions from trading partners has not been very successful. At best, tariffs and tariff threats have resulted in concessions about 50% of the time and the concessions have been meaningful in terms of achieving the objective at about a 40% hit rate. However, these attempts have been pretty small scale attempts. The Administration's experiment is on a much grander scale. It could work or it could result in another Smoot-Hawley episode.
5) Finally, the focus on bilateral trade deficits is misplaced. I run persistent bilateral trade deficits with Publix. I buy a lot from them and they buy nothing from me, but what matters is my overall spending behavior. Similarly, it is not a surprise that the US would run persistent bilateral trade deficits with a country as trade is driven primarily by comparative advantage. What matters is the overall trade deficit and that is driven primarily by macroeconomic factors. If we want to reduce our trade deficits then the US needs to increase private savings, reduce government deficits and the trade deficit will begin to fall. There are other things could do like impose capital controls or manipulate the exchange rate, but meddling in markets is unlikely to have unintended consequences.
These are some of the points that are included in a presentation that I am working on today for a talk later this month.
1) A tariff is ALWAYS paid for by the consumer, not "mostly being paid". Think of a tariff as a form of direct taxation, i.e. even if a corporation has to pay higher prices from vendors, the prices are directly transferred to the consumer.
2) There is no precedent in history that demonstrates where higher taxation (tariffs) results in higher employment (long term) in the PRIVATE (not public) sector.
3) Again, a dramatic (25%) tax increase would logically disrupt any consumer good, auto or anything else for that matter.
4)When tariffs become a mechanism (a from of financial war) for "trade", the currency used for trading has begun its fight for its very existence. Hence, massive debt, massive "printing" or currency creation, massive government "funding", i.e. housing, food, energy, etc.. In other words, when the government of a country literally becomes the "pillar" of economic "stability" and the private sector has been supplanted, the game over moves are right around the corner, hence, tariffs are just the beginning.
5)Your analogy is misplaced. Bilateral trade deficits are usually meant to describe an exchange of goods (possibly some services as well). What you are missing is, the US doesn't produce ANYTHING in our arrangement with China. We exchange currency (no goods whatsoever) for products! Theoretically, Americans could all sit on their collective asses, not work, the government create currency, and all of these countries we run "deficits" with will ship us everything we need. This is dramatically different from what you are attempting to describe. The US can never stop this arrangement or even decrease it in the slightest. If we attempt to decrease it, the export of currency MUST shift to another holder of debt or its game over, the tsunami of currency will come flooding back.
I suggest you focus your presentation on currency creation, the unintended consequences of its creation and the result of its creation. Tariffs are a mute point vs currency in the grand financial scheme of things.
