Some people do enjoy assembly line work, and in fact I would say a large amount of people want a reliable job with minimal mental overhead. There’s a lot more industry wants though: welders, safety personell, repair techs, engineers, chemists, programmers, electricians, hydraulic specialists, all just depends on the company. A car manufacturer for instance prioritizes robotics, but a steel plant would prefer welders and machinists. Tons of opportunity for people to do the jobs they love for good pay and benefits, if we could get more manufacturing into the US.

Right, but it's the converse that is the issue: Americans wanting to do jobs that aren't found (or only found in a limited way) in America. Trump also supports them. The intent is to see things like manufacturing jobs happen more often on American soil so that Americans can do those jobs.

> Is that really a passion for many people, working on an assembly line?

The idea of it is, at least. I know a lot of people who have impressive manufacturing facilities in their garages just to support it as a hobby. Manufacturing is clearly a relatively common passion. You may have a point that they might come to hate the work if it became their daily reality, but the emotions that drive this sort of thing are never grounded in logic. Besides, it is not like they love the burgers they are flipping right now.

That's a great point. Legal immigration (to somewhere desireable) is not an option for much of the population. What interest do they have in preserving it?
