Fair trade certification (y'all might recognize the logo):http://www.fairtradefederation.org/
This is a complex issue, and one I've struggled with a lot from a manufacturer's perspective. I don't think that sending work overseas is inherently unethical, and hence have had to make some very tough decisions for our company. What it comes down to for me is that if I can find a "neighbor" who has the skills or products that I need, my personal ethic says that I should use them. That's a big IF these days, for many things, like fabric. (We use as many organic fabrics as possible in our products, and we're down to ONE domestic organic fabric mill making prints at all. And only 2-3 domestic mills making (yawn) solids. So it gets harder by the day to keep much of our sourcing in the US.) But I DO know that I will not send my products overseas to lower the price. I'm proud to pay my employees a living wage, and I'm proud to work with local contractors who pay their employees living wages, and I feel fine passing that cost on to my customers.
One more thing to add to the mix is transportation costs, financial and environmental. When I factor in the fossil fuels and such to get a product from China to Texas, then on to the consumer, the "cheap" price of goods doesn't seem so cheap.
