Sure, but regarding wages, there’s no place to go after China. Do they want slaves?
There are at least 100 countries with lower wages than China. That’s why I mentioned “comparative advantage”. In this case, what matters is productivity/dollar of wages. (Where productivity includes quality of the product.) To simplify somewhat, Chinese workers make 3 or 4 times more than Vietnamese workers (on average), because they each produce at least that many times more goods or services.
Actually, there is. China has been outsourcing to South America. Foxconn was so overloaded that some iDevice production is being carried out in Brazil.
