Saunders is a hilarious guy. For the last weeks he's been telling us it's all evil middle class white people. 

Now he's wringing his hands because something has just occurred to him. And you can see he's painting around the edges here but doesn't want to outright state it - immigrants can be some of the most racist groups you will ever encounter. Think of all the wars and conflicts in the world the west hasn't started - they do exist! The hatred and prejudice that started those battles isn't left behind, it usually comes with them to their new countries. Shocking, isn't it? I remember sitting in a taxi where an East Indian guy absolutely assailed people from the horn of Africa the whole ride and I couldn't get a word in - this is reality.

Of course Saunders is trying to make the case it will be old whitey exploiting the naive immigrant (as if that's not racist) for his nefarious ends, but a lot of immigrants are only too happy to pull the ladder up once they're on board.
