Im all for good american manufacturing jobs, whatever jobs, good jobs. I just don't see how you get them out of a tariff. I think the businesses should be investing in making their own workers more productive, maybe this will be incentivized if production has to be at home? Possible.
Using this :

Average auto worker makes about $65-95 an hour? The average mexican manufacturing worker makes $2 an hour? So I guess I dont see the small benefit, it seems like a huge one potentially, though, I of course dont know the levels of productivity for these different workers, just their wage rates. But so even if labor cost is currently only 10%, aren't we trying to add more of these jobs? Won't there be a point in the calculus where the labor slack is no more? Where wages rise and therefore that 10% rises?
All not factoring in at all that current production levels are a mixture of different places. 50% of the production cost is in making the new plant. Not to mention the 20-30% cost of materials. Where do the now american only produced cars get their materials from, only at home? I don't even think we have the raw resources for this I could be totally wrong though. If theres a 30% tariff or even the 20% import tax across the board, all those materials, used in american production, would also be more costly no?
About 6 million vehicles were made in the US. About 2 million were "cars", while the rest are commercial vehicles. (
http://www.oica.net/category/production-statistics/) Nearly 7 million were bought, from what I can tell these are regular passenger cars.(
https://www.statista.com/statistics/...es-since-1951/). Thats a lot of calculus to change. A lot of input prices to figure out and labor levels to optimize for given you want to produce 5 million more cars and will probably have to incur capital costs to up your level of domestic production. Of course look at car production around the world. The us makes way more motorized vehicles than mexico. You will notice though, that more passenger, instead of commercial vehicles, are produced in Mexico. Theres your comparative advantage, not the tariff. Advanced manufacturing sectors that are more productive but offer fewer jobs are also an american comparative advantage currently (and to come).
I suppose you can say the tariff is needed to make sure these jobs dont go to mexico? Ok sure maybe. But remember, only 1.7 million cars are produced in mexico. 12 million produced in China. Oh look we produce many more commercial vehicles while they produce more passenger...interesting. I understand wanting to protect the well being of the people in your country. But when all you look at are raw aggregate numbers youre not doing that. Youre not accounting for the nuance of how we can be the second largest car producer in the world, and still import more in terms of dollars of passenger vehicles. You're not accounting for that, if you really want to shut off, ok, but the kinds of cars and production capacity we have here is different from other countries. We can definitely produce 7 million passenger cars a year. The question is the cost. The question is how will the now tapped (after we increase passenger car production by 5 million) labor supply and need for capital investment to raise production capacity changes the costs within the American market. Unless we are assuming our current production can be traded one for one with no cost? maybe.
Anyway Id love to see you actually doing the calculus problem, if you have access to these production functions in a way most don't.
Your short run calculation probably works. The long run (in which capital can change, ie number of factories ie 50% of the cost) is why the 30% tariff is not enough, and the ensuing change in production techniques and labor market, and changes in consumption and price levels. Also again, if we are shrinking the pie of the world, who will buy our exports? You can make a closed market I suppose, but have you calculused out the options and costs of that?
TLDR you are not accounting for how exogenous parameters will change in the long run and then influence the endogenous variables of the optimization problem
