Wouldn't the surplus profit just go to the CEO of of the company? I can't imagine there's much difference for the average worker in China between mass manufacturing PC's for direct sale vs. Mass manufacturing for another brand.
I don't believe there's many worker coops building PCs, unfortunately.
I don't see that as any more desirable than a US or Russian CEO doing the same. It's all wage slavery for the people generating those profits, and it's all gravy for the CEOs to funnel into offshore accounts. Only funding a worker coop would make it more ethical and desirable, regardless of geographic location/regime, IMHO.
