I think this is eventually inevitable. After India (which is only marginally cheaper than China) Africa is the largest reservoir of potential cheap labor. When that's started to experience wage inflation there will be nowhere else to go except automation, and automation is generally oversold and is a lot harder than it seems. It's easy to automate the most repetitive 10-20% of an industrial process, but exponentially harder and/or lower margin as you move down the long tail. Most people aren't aware of just how much of the stuff they buy is still made by hand.
