Everything wrong and right with the author's thesis. Our present day high-end manufacturing, agriculture, and innovation are already facing the steepest tariffs from a broad range of countries. The uneven playing field extends to IP theft, heavily subsidised and protected industries abroad and other forms of unfair competition like port traffic manipulation or burdensome legislation.
The author think that "targeted tariffs" would have a different effect from what we see now with trade war and retaliatory threats, market instability and uncertainty. This is false, but also ultimately harmful to our "agricultural drone industry". It's hard to have a niche industry without the larger picture, and it's hard to have "drones" without knowing how to manufacture constituent parts and having a reliable domestic supply chain for such. A domestically sourced supply chain encourages innovation and adaptation to immediate customer demands and goods can arrive in days or hours instead of weeks or months. Innovative requests to parts makers aren't immediately harvested by Chinese industrial spies and knowledge and technological advantage can remain local for longer, allowing for time to progress again before others can catch up.
Encouraging lazy and unoriginal drone manufacture in moated "made in USA" assembly lines is precisely the low-end type of job that "no one wants to do" and will inevitably produce the least capable drones the least efficiently or profitably. Our manufacturing and industrial capacity needs to be the world's best and most cost competitive because nothing else will do.
Only automation can save American industry. There will be "fewer" jobs but they will require skill and training. Robot management and supervision and repair and update and retooling will all require a large labor force. Creating robots and the software they run on will continue to be an important and large sector of the software industry. But manufacturing is only about jobs in the way that having a healthy agriculture industry is "about jobs", hardly at all.
Manufacturing real goods is the difference between servility and freedom given that modern war in the nuclear age also entails producing billions of tonnes of metal and blowing it up in distant countries, and could require replacing percentages of the global shipping tonnage that would be destroyed in a major conflict. It requires manufacturing thousands of substation transformers and the aa systems to defend them.
If we had invested strategically into a variety of heavy and light industries over the past 30 years, we almost certainly would have invented better processes and formulae for making things than we currently possess. We could have more globally competitive steel, even more advanced finished products and the knowledge and experience to "make anything better and more profitably than anyone". Industrial production and manufacturing make up roughly 15% of US GDP today. "Bringing back manufacturing" might increase that number significantly but it's hard to see how or why it would need to be more than 30% outside of wartime. That wouldn't even require a doubling of the jobs involved because much of this would have to be automated.
I agree with the author's emphasis on education and "fixing" things being critical in the execution of any kind of industrial renaissance. If the tariff fight lowers tariffs globally, that is a small move in the right direction of leveling the playing field and rewarding domestic producers who are globally competitive.
