anecdotally:  a friend has a furniture business.  He set up a manufacturing plant in China.  Aside from poor quality and slow delivery, a common occurance was the arrival of recruiters on the lunchtime buses, taking a number of his workers away in the middle of any given day.  He is now manufacturing in Louisiana, at lower cost, with higher quality and quicker turn times.

He isn't alone in this story.  It seems every week I hear of another company bringing manufacturing back from China, yes, to the US, as companies realize that salary isn't the only cost.

Just this week, we pulled a PCB design and a plastic design back from our Chinese R&D team and gave them to US contractors.  It was costing us too much to pay them 1/3 of our salary.
