I've posted this on another thread too. It seems appropriate to re-post it on this one:
In my continuing search to try and find out what drives racism and xenophobia, what helps the rise of right-wing populism, I found this article, entitled A Few Quick Thoughts on Brexit, by Chris Arnade in which he argues that "The language we use to talk about those who have been left behind [he means the poor] is rife with nasty attempts to turn them into lesser humans. We use the tactics of racism, and apply it to economic losers".
As he's American he lists the sort of terms used there: "We call them dumb. Idiots. Religious freaks. Rednecks. Thugs. Hoodlums. Ghetto trash. White trash".
He says elitism and inequality are racism's ugly cousins and that they drive people to racism and fascism by undervaluing the less successful: "Fascism understands that people want to feel valued and integral part of something larger. Racism is, sadly, the easiest and cheapest way to do that".
Reading the article will aid understanding of his point.
