There was an interview with the local marketing managers for Coca Cola and Pepsi when I was a kid. I vaguely remember it (and also the idea was somewhat foreign to me since the world had just started opening for eastern Europe and it was the first time many of us heard the names such as Coca Cola, McDonald's, etc). The one thing that stood out was the Pepsi manager raging about campaigns, failed products and whatnot. The Coca Cola manager calmy looked at him and said: "Sir... Look at our product... Who in their right mind would pay for a rusty-colored liquid as a beverage? Absolutely no one. It's all about the advertisement".
Same story here - would you buy a pair of shoes from anyone, seeing the horrible conditions they work in, sleep deprivation and poverty if you knew they'd still get close to nothing? Probably not. You see a fancy store (or website these days), you see a product you like and you're invited to open up your wallet for a fancy pair of shoes. Deep down you still know they came from the people working in horrible conditions but, you know, out of sight, out of mind. And thus, you are willing to pay the extra price.
