No but it's presented as the major problem to solve. There are lot larger issues at play and if keeping pork workers buys is the goal, then we should have them load and unload empty boxes /s
I don't think OP was specifically stating we need to save these specific jobs, rather they were pointing out the interconnected nature of the economy. Less importing hurts the workers in those industries. Taking that further, it will hurt businesses near the ports where the workers may have gotten lunch, etc. etc. etc. That's how recessions look at a microeconomic scale.
