you have to read the labels that's for sure, I am often surprised to see a lot of things made in America that I would not expect to be, Bic lighters from Walmart, it's not even an American company yet they are made in America. Things like iPhones are made in china because Chinese people work cheaper than trying to retool an automated assembly line every few months when a new model comes out. But something like tube socks that are mostly made by a machine and don't change much over time are available American made. But if you are not careful they will be assembled in America. America produces a lot of raw materials, oil, lumber, cotton, corn.  The only things it makes sense to outsource are those that are very labor intensive to manufacture. As robots get more flexible cheaper and easier to program Chinese workers will become obsolete.
