What makes for a good inference?

Injustice is injustice no matter where it happens.
The reality is that masses of people in third world countries are exploited and they don't have very many options to do otherwise. The governments and multinational companies are very interested in maintaining this status quo -- that is how you can earn billion (get cheap labor for low costs and sell at high prices).
Apple doesn't sell their products at 1/5th the price in the US to reflect the local rates (for that matter most things like a Mercedes would sell for the same international price). The point is that a large section of world population is denied many benefits simply because where they are (think about the quality of medical treatment in the US vs a place like China or India or Uganda).
It is in one's interest to ensure access to all such services/products at low cost (subsidized by someone else) while ensuring comparatively high compensation due to residence in a first world nation.
Hopefully the inequity will grow smaller over time.
