An Algerian came illegally and voluntarily to live in a pigpen, assisted by human traffickers posing as rescuers, and we tourists are supposed to feel sorry for him and feel guilt?
It's not champagne and oysters others consume that are causing this man's ruin. Deport him - problem solved.
If an Ibiza native somehow ends up without a roof over their head due to some tourism excesses and without own guilt, this should be looked at. But poor migrants shouldn't blame rich migrants and tourists for their misery - they could have avoided all this by staying away from the island. Can't this guy just go to a police station (or whoever deals with migrants) and tell them he wants to return to his native Algeria? Many countries would have happily given him a free ticket home in such a situation.
