What is made in America? Not my GMC pickup. It was made in Mexico.
Hopefully without being political, here goes. When were electronic devices, be they televisions, radios, computers, recording devices, etc., last made in significant numbers in America? What about shoes, furniture, textiles, and clothes?
You can buy fresh fruits and vegetables year round. When I was a kid, produce was a seasonal product. Apples in the fall, oranges in the fall/winter, grapes, peaches, plums in the summer. It is now possible to ship produce around the world and deliver it to the supermarket shelves. Unheard of when I was a kid.
Communications are instant. Business moves, literally, at the speed of light because of computers.
Another factor, world markets have changed dramatically. That necessitated businesses to adapt to changing markets in order to compete and survive.
When I was a kid, America was an island when it came to manufacturing and consumption. Overseas competition regardless of wages and regulations just was not practical because of shipping considerations alone. That has all changed.
In spite of that, foreign auto companies have found it not only practical, but profitable to manufacture vehicles here. There are several reasons that has happened, but the prime reason is that as these companies grew in the home countries, their labor forces were no longer satisfied to work for "low wages". Costs of production increased in those countries, and no doubt their governments viewed them as a source of revenue as much as a source of jobs. Add transportation costs, and it became practical to open plants in America.
Isolationism may have been fine in the past. It's a recipe for disaster today.
