But what happens when we pass laws in our country that takes away the job in another when there is no realistic chance of them implementing some safety net to help? For example, when western countries put pressure on east Asian sweat shops to stop using child labor, they did, but the local governments didn't offer anything to help the children who depended upon those jobs to have enough to feed themselves, and as such many of the children transitioned into even more dangerous jobs or worse. It would be nice if their government made up for the gap, but int he real world we have to deal with the possibilities they won't. So one has to deal with the ramifications of their choices that shouldn't and wouldn't happen in a good world but do happen in our world.
