This discussion also got me thinking about something. While that Jacobin article sounds likes a pretty fair assessment of the mainstream Democratic party's beliefs. I think it's also true that, at least in the United States, leftists who would never associate with the Democratic party embrace what seems like a similar line of reasoning. For example, I'm sure some of you are familiar with the book Settlers by J. Sakai (

I admit I haven't read it (I plan to very soon) but I've heard it come up a lot and my understanding is that basically Sakai argues there is no white working class in the US, that the whites often called that are more accurately labor aristocrats who have historically exploited the labor of non whites (who are the real working class in America). I am not sure what Sakai himself argued about whether or not one should bother organizing labor aristocrats or not but it almost always gets brought up in left circles I've been around as a basically infallible book filled with reasons to ignore the concerns of working class whites.
I know most of you are UK based but have any of you engaged with this debate in general or have any thoughts?
