Does trade benefit the rich & the poor?

source: economist.com 

KEY ECONOMIC PRINCIPLES I’M ADDRESSING: People gain when they trade voluntarily.

OVERALL RESEARCH QUESTION: Are trades between rich and poor countries benefiting both sides.


SUB QUESTIONS: Do rich countries try to take advantage of poor countries? Are poor countries relying on rich countries for economic support? Can poor countries also take advantage of rich countries?
