"All-American" content is not smart
I want to make a good machine. I'm not going to compromise the machine design just to make it "All American". If an American company makes a quality product that fits my requirements, then there's a good chance I'll use it.
And, unlike most of you, I am involved with selecting components. Most of our parts are from the US, Japan, and Germany, with some stuff from Italy, France, Switzerland, Taiwan, and, yes, China. For example, for our needs, Panasonic's micro PLC's fit our needs (and budget) much better than anything from Allen Bradley. We use sensors from Italy that have no equivalent anywhere else in the world. And so on.
BTW, most of the world is similar, e.g. few things "Made in China" are 100% made from Chinese components. In disk drives, for example, Hutchinson (USA) makes about 70% of the suspensions (and they are made in the US) while a Japanese makes most of the spindle motors. So a disk drive may be assembled in China or Singapore, but its parts come from all over the world, including the US.
