Many immigrants appear to be indignant that they are not allowed to go where they like - cries that they "are not animals" heard when overloaded facilities break - scant gratitude for y'know, not being shot at and whatnot.

If they really do think that there is practically a concierge waiting from them to help them to their new house and job is it any surprise that they're coming over? There have been many migrant streams through the ages that were caused in essence by the people involved being misled.
