Funny I have as much trouble with USA made products as I have with foreign made products. Though having failure on a $500,000 piece of farm equipment is a little harder to take than a $400 toy train.
Personally I don't care where the product is manufactured as long as the price is what I am willing to pay or can afford and the thing works. I don't care about the little things that go wrong that is going to happen. I don't think I ever bough a vehicle or piece of machinery made in the USA that didn't have to have some type of warranty work done.
Lets see the Jeep has been back for 5 different things in its warranty period and I have a hay baler that needs work done every time it bales. While these are all made by union workers they last no longer than non union products.
Now to my trains nothing ever had a serious defect other than one MTH engine that had a flat spot on the wheel. The LHS just replaced it with another one. I was lucky he had more than the one I had just bought. Other issue were electrical again on two MTH engines. No big deal one had wires that had come out of the wire nut and the other had a short in the trucks. Both easy to fix and not worth sending back.
People get excited when something needs just a little tweak. When talking to my father he said things were much worse in the 50's and 60's. Heck things back then could even kill you because they didn't ground most of the electrical stuff like they do today.
Not everything is made overseas in fact all the computers I have had were made in the USA and I am on my fifth one since 1997. They all had a major failure though my printer made overseas has been chugging along for a very long time.
I would certainly like to see more products manufactured in the USA while I believe the failure rate would be the same at least we would have more people working.
BTW during World War II there was a company that built gliders for the army. The workforce was 90% women. On the day that they were going to show case it in front of the army, townspeople and press they had a major failure. Once it was released from the tow plane the wing broke off and killed 6 people including the Mayor, a General and some other VIPS that were riding in it. The reason for the failure was a bolt and the woman who inspected it did not realize the key importance of the bolt. Thus it isn't really truthful to say that the change in the labor force during the war did not result in some very bad accidents. I forget the name of the company and town but I will check on it and post that info later f your interested in the story.
