I'm really sick and tired of "but they're happy to have the abysmally low-paying job, because in their currency it's above-average!". Companies like Facebook aren't outsourcing to "give jobs to the needy"; they only do it because it's disgustingly cheap for them. The destitute, desperately grasping at the crumbs dropped on the floor by the rich, is not a positive thing. It's depressing.
What's next? Do we defend companies who hold immigrants' passports hostage, enslaving people indefinitely with no way out? After all, they pay X% above average! Those workers should be thankful just to have a job! Who cares that they'll never see their family again, and likely die while living in squalor?
