I do care where my stuff is made, to the point I'm willing to pay a premium &/or sacrifice a few features.
If it's only 40% or 60% "made in the US?" I guess my thought is that's better that 0%.
My reasoning is completely selfish though, and I'm sure has an element of "lost cause" to it. I live in the US. My thinking is the more people that have jobs in the US, the better off I'll be.
Let's say I live in Boardman, Ohio & I like toy trains. I'm going buy the Ameri-Towne kit over a foreign made brand... even if the foreign version is cheaper and nicer. Why? There's a guy that works at that plastic factory in Boardman. Because he has that job, he gets a paycheck. With that paycheck, he pays property tax. Those taxes pay the teacher that teach my kids. He also uses part of his pay to eat at the diner my wife works at. He uses part of his paycheck to buy insurance from my buddy. He uses part of his paycheck to buy widgets that I make in the Widget factory on the other side of town. He even uses his paycheck to subscribe to OGR.
When the Boardman Plastic Factory shuts down. He, and all his coworkers, stop buying all that stuff around town. The schools go down the tubes, the diner shuts down, the OGR guys wonder why their subscription rates stink. Then he goes on unemployment, and we all get to complain about having to pay for him to eat and how evil CEOs and the government have ruined the economy (while we drive our Japanese cars & play with our Chinese trains). Then we get on the OGR Forum and wonder why the LHS shut down.
