'Some' workers are displaced by the chinese, 'some' by the indonesians, 'some' by the Mexicans, 'some' by the Sri Lankans (sp), 'some' by the Brazilians, 'some' by the - well just read the labels on your products.

The key has been to open more markets which helps more people of every country. As markets are restricted more workers worldwide are hurt.
