I think every single one of us on this forum would have to think very hard about changing our lifestyles. Right now we don't even KNOW about the grinding poverty, sickness, and pain that is caused by our economies in other places in the world. When you bought a shirt, you would feel the sweatshop worker's fatigue, and taste the water polluted with bleach, etc., etc. This kind of foreknowledge would have the potential to structurally change the world, not only change ou individual actions.
