When looking at any fuel consuming product, such as a tractor (large medium, or small) or a car, truck, or even an airplane, that is "Made in America" you are usually looking at something that was assembled in America from parts that are sourced from within and without America.
Some products are mostly assembled here from overseas parts like many midsize tractors, and some, like Boeing's airplanes, have a large American made content. But don't think for a minute that Boeing's planes are 100% American made.
Even a lot of our military hardware has components made overseas, but (thankfully from a security standpoint), that is still a small percentage, notwithstanding the recent USAF tanker award to Airbus.
We live in a global economy that is very different from the economy most of us grew up in, and no one is capable of turning back the clock. Best you get used to it, just like we are used to not seeing elevator operators or gas station attendants (except in NJ -- what is with that anyway) anymore.
It's too bad MessickFarmEqu felt he couldn't post to this thread. I, for one, have always appreciated his insights.
