For me, the really vulnerable in society are the hard working people who are just above the benefits system, who earn only slightly too much to receive much help or support. When taxes go up to pay the benefits for those below them income wise, or public sector pay increases, or bankers bailouts, or expensive train lines to Birmingham etc., then they are the ones who are really and disproportionately hit.
They used to be known as the JAMs- just about managing. These days, they are the slowly drowning. And not that slowly, either.
