Much of that improvement comes from those countries internal economic policies
You really don't think that trade deals with China did not help Chinese workers? I thought that was what people are complaining about: Exporting jobs to the developing world. I would think that if you export a job to China, somebody in China gets a job. Forgive my naivete.
Forgiven. You assume that paying slave wages improves the poverty level? There are dozens of examples where the mere existence of jobs, exported or not, do nothing to improve the station of those workers. In fact, exporting jobs generally goes hand in hand with low wages as a way of cost reduction to the international capitalists.
Usually said improvement comes about as the result of a more equitable internal policy of the distribution of wealth. Or better internal social programs that protect the citizens.
