Not really, they are constantly raising the issue of zero-hours contracts. Nobody in the Labour Party talks about coal miners because there are none left.
I didn't specifically mention the Labour party (because they are not the only socialist group, and also within my life-time were considered a centre-left party) and don't like party-politics on HN, but it seems to me that coal mining is still a big part of their identity[0].
I also wasnt talking about zero hour contracts at all???
I hope HN doesn't become yet another arena where you can't discuss broad categories of political theory without being savaged by Corbynites.
