If you do not understand economics you do not understand the big picture and how the tariffs will effect different inductries and industries compared to individuals.
The one industry may find increase in jobs in a relatively short time. There are empty factories that can be started up fairly quickly, moving manufacturing to the USA from other countries. No other industry has prebuilt infrastructure (factories) to move into. They have to be built and skilled labor is required. That takes time.
As the automobile manufacturing moves to the USA, many parts have to be accessed through other countries. The tariffs will make those parts more expensive. Thus cars will be more expensive.
The reason much manufacturing is outside the US to save money. As manufacturing moves to US, higher wages and higher cost for cars.
The UAW could do well. A unique situation. But the cost of cars is going up. Inflation
