The governing principle I use when making purchases here in the U.S. is American made first, then secondly; countries that are allies of ours with similar wages, environmental standards, and trade practices....when possible! Further, I let the proprietor know of my displeasure when I can't find an item that I need that isn't made in China, Russia, Pakistan, Vietnam, Taiwan, or Lower Slobovia. I may be pissing into the wind, but if a billion grasshoppers all pissed into the wind simultaneously, well, one could only imagine!
