This article doesn't define what being working class means in the modern economy. If you're a freelancer who can't afford property, doesn't have basic rights like a pension and sick pay, and whose entire income could vanish overnight, what class are you? https://www.theguardian.com/commentisfree/2021/jan/18/why-professional-middle-class-brits-insist-working-class
What the pandemic has shown is that many people working in professional industries (like the arts, which is an example in the article) are only one policy decision away from destitution. We need better ways of defining our class system before we have these conversations.
Anyone who doesn't need to work because they can rely on family money is obviously middle class. But I also think a freelance graphic designer living in rented accommodation with no job security is more working class than a retired plumber who owns a house and two cars.
If you earn £24k a year, are you working class in London but middle class in Blyth Valley because of the difference in how far your money stretches?
OK I'm done but my basic point is this: I think class needs to be used to identify a group's shared economic positions and interests, and should not relate to accents, preferred newspapers or lifestyles. The current ABCDE definitions of class are outdated.
