As the world economy blossomed during the last century, opportunities in modern manufacturing have spread over the entire world. Many peoples of the world have embraced that opportunity to better their situation for themselves and their children. For our part, we have helped, and profited, by off-shoring work to most of the rest of the world.
However, given the current situation of increasing governmental belligerencies throughout the world, our supply chains can be held captive by rogue actors and governments. It just makes good sense to on-shore as much of our manufacturing as possible for myriad reasons.
One, we have nearly lost all of the talent that created the worldwide rising tide of opportunity. Most have retired and those that remain are few and far between. Thankfully they've trained a few of us younger folk that have now come up through the ranks, although our numbers aren't sufficient to manufacture all that we need.
Two, automation has now reached into the very heart of manufacturing. If one can write a big enough check, one can acquire, out of a box, a complete, self-inspecting, robot loading and unloading machine tool, capable of running day and night with minimal human intervention. -assuming one is or has a darn good programmer.
Three, overseas shipping is one of the worlds heaviest polluters, posing multiple risks to the environment. Not to mention the human and environmental costs of manufacturing in places that have minimal, or no, human rights assurances nor EPA.
