I agree, but we would have to be willing to pay for that. I'd bet if AMD had a plant here, the cost of any given panel would be double. Regulations on chemicals, that is, paint, etc; taxes on businesses. You know what I'm saying. This is the #1 country on earth, with a high standard of living. Labor and material costs are correspondingly high here. This is a hobby for most of us, i.e., disposable income. When times are tight, hobby costs are the first to go.
Here's a real-life example: Some years ago, I was shopping for a beach chair on vacation. I found the usual Chinese ones for $20-40, and a group of ones with a big "Made in USA" tag on them for $90.- I looked over the chair, and seeing the rivets at the hinge were the same size as all the rest, I went with the cheaper one.
