If your in the bottom 1/5, your going to be pretty close if not below the poverty line. I'd hardly call it exploitation. US companies there don't pay workers as much as they would in the US, but still pay more than other jobs in said country. They'd be worse off without us there. The article is about the US anyways, not other countries. His supermarkets/groceries argument is way off the mark. And its true that the main reason for increased prices in the inner cities is because of theft. Poor people steal things for stores more often than rich people, you'd be idiotic to debate that.
