There are legal definitions as to what "Made in USA" means. I doubt if every raw material needs to be domestically sourced. For stainless steels, many of the elements are in trace amounts, often less than 1/2 of one percent.
But I think the Made in USA sticker does generally suggest more attention to quality but that is not guaranteed. I personally have a pecking order of countries which I will support, and China is pretty much at the bottom of the list. Not just because of its generally inferior produced products, but also because it is a communist, police state, dictatorship that with a billion people to support will likely have global ambitions as it becomes more powerful.
I really wish people would look at the label and see where the product is made before heading to the cash register. And yes my wife, I am looking at you.
