I don't know that I agree with this. The US is too large a market to ignore, and this is effectively raising the profit margin for local production. Foreign companies will either move some portion of manufacturing to the US (for the domestic market), or cede the market completely, and I don't know that they're prepared to do that (well, maybe Chinese ones are). Factories have a long lead time, so even if this is abolished at the end of his term, they'll be locked in with sunk capital costs. The main reasons not to do this are a) abandoning the market, as mentioned, or b) you think you can hold out long enough until the political landscape changes. If the people aren't there, wages will rise until they show up. Most labor shortages aren't an actual shortage of labor, unless you genuinely can't produce that skillset domestically, or your labor market is so tight that no one is unemployed; rather, they're a shortage of wages. Pay enough, and someone will do the job. This is especially true for low-skilled work. There is not, and never will be, a shortage of cleaners, for example, because anyone can do it, so as long as there are unemployed people and the wages are good enough, someone will do the work. And even if these jobs aren't in running these factories, they've still got to be built. Money is a powerful motivator, so I have no doubt they will. Companies will bleed because of this, but there are clear benefits for the US working class even if they're paying more. The gamble is obviously that the benefits outweigh the negatives of higher prices overall. Modern economics says no, but modern economics also believes in service-based economies, and that countries should only produce what they're good at, which, eventually, becomes a repudiation of the nation state. No country wants to buy bullets from an enemy, even if they're cheaper, and the web of infrastructure and industry necessary to maintain a defense industry mandates that at some point, you abandon the theory. Which is to say: I don't know, but I'm also skeptical that economists do. |
While this might be in a theoretical and pedantic way true, sometimes you do not have the economic context to provide those larger wages, so there will technically be no "shortage" - but just because the jobs themselves will disappear.
If you look at poor countries or regions, there is garbage, dirt and dilapidation everywhere. Clearly there is - in a practical way - a need for cleaners, but by your definition there is no "shortage" - because they cannot afford to pay anything for those jobs.
