I guess London has a similar problem but not this serious. Living Wage Foundation calculates yearly the living wage for London and there are around 4k companies that pay it voluntarily. Maybe a similar solution would be useful. I'm struggling to understand why the these people living below the poverty line don't just move to a place where rent doesn't eat all their salary. They must be trapped in one way or another.
