It'e economics, folks. Plain, pure, and simple.
The goal of any enterprise is to maximize return while minimizing operating costs. No different than your own business or household. Unless you expect the neighbors to hold a grudge against you for buying your gas at station X or your groceries at store Y......you can't likewise carp when a product someone else buys is made out of this country. That would be unadulterated hypocrisy.
Now, I'm no J.D. fan. But this is not by any means whatsoever the first product sold and marketed in J.D. green that is foreign sourced. Hehehe.....not by a long shot. They loved Zetor in the 1990s and they made them some darn good tractors. A lot of Green-Weenies jump up and down and hoot and holler about their Green Zetors to this day and don't have a clue that they are former Eastern Bloc...
