Powerful article.
Like many (as I see in the comments) I recognise that prejudice in myself. It is part of that awful thing of having "others" to look down on, to blame. It's finding a way of blaming the homeless for the cost of welfare, when the vast majority of that money (90%+?) ends up in the pockets of a few billionaires.
I am more nuanced in my prejudice as I understand it better, and I try not to be unkind to anyone, but I think it's a prejudice that the world needs if it's to become a better place.
