In 2004 Michael Collins wrote a fascinating book, The Likes of Us: A Biography of the White Working Class. It was part memoir of his south-London childhood, part history of the area and part polemic. Two-thirds was an excellent read, a thoroughly researched and well-written account of the many generations of his family who had lived in Walworth, but the last third was a confused mess of an argument about what he saw as the plight of the modern-day white working class - marginalised and despised by the middle-class media and forgotten by the establishment. I had a similar response to this programme; it was meticulously researched and engagingly presented, but had at its heart a deeply flawed conclusion.
