This is one part of the movement that I've never fully understood. Yes, yes, it's all well and good to not have had to ship things from overseas, but there is very little industry in the U.S. And what guarantee that you'll have high quality just because it's "american made"?
A fellow blogger mentioned how she was going to buy art supplies for her kids, American made if possible. My first thought was: when I think of high quality art supplies, I don't think U.S.A. I think Germany, or Italy, or someplace that has a strong art culture. I'm sure that you can FIND U.S. made art supplies, but that I fear they'd be lower quality, and not worth the money.
Because so much has been shipped overseas, there is usually only one or two of any given field still operating in the U.S. That does not give you a lot of options to work with. Suppose you're buying a tool -- you want a tool that will last a long time, not break easily, and be easily repaired when needed. If you only have one or two options, you better hope that they're good! Especially as the dominant culture in the U.S. is the "break it and buy a new one within 6 months" mentality, which does not a good tool make!
I just... don't really get this.
