The UK’s (democratic socialist) Labour Party have many policies specific to the gig economy and zero-hours contracts, training, and housing for young adults. I haven’t heard them mention coal miners in a while. I’m sympathetic to much of your comment, and policy gets reported far less than parliamentary pantomime, so if you’re not trolling and are genuinely unaware, take a look[0].
I have no interest in a long thread about how the policies make people on HN feel. But it seems worth pointing out that the ‘precariat’ are a primary issue for Her Maj’s shadow cabinet.
