It is an eyeopening experience to go to YouTube and type in monster machines, or automated farming. Go watch timber being cut for hauling in seconds. Maybe someone could find it interesting that railroads are being laid with machines requiring a 5 man crew. Or watch a monster bridge being laid by machines.
There is a video on the tallest bridge in the world, fascinating stuff that few people even know exist, or they wouldn't be saying we can't build a wall.
The idiocy of modern immigration proponents - “we need low skill labor to pick crops” while we’re building more and more machines to make them obsolete while having no plan to deport the now obsolete farm labor.
