I thought Mary Ridell's analysis was what you might expect from somebody paid to write articles with historical pretensions.
This isn't about the underclass. It's almost entirely confined to young people - young people who are adept at 'cloud' organising, want stuff that they think is nice, and have no particular fear of being caught. If you seek a comparison, then look no further than other more elevated social networks - doctors, bankers, architects, lawyers, or even the Department for Transport. A group unites around an opportunity and exploits it with the aid of encoding, heedless of the consequences to the rest of the citizenry. It's amoral, messy, and individuals suffer. It might have happened last year, or the year before that. It's part of a general, shared malaise, rather than a reaction to it.
