I can understand why you feel like that, but it isn't the zeitgeist, mate. It's just a discourse some rich fuckers are trying to impose so that they can carry on robbing. The reason so many decisions get overturned on appeal is because the Social Security Commissioners (on whose work the Tribunals base how they make their decisions with regard to individual cases) deal with law and precedent, not with zeitgeiste or discourse.
I'm not sure whether the process has changed yet, but IIRC you have to request a review of the decision first. Why not mail them asking for a review, and requesting a copy of your assessment? That way you can see whether they've cocked the assessment, and whether they've done it enough to warrant going for an appeal.
