Obviously the quote about low morale is just nonsense but he does make some interesting and even valid points. I came from a home plagued by unemployment , deprivation , neglect and criminality. My teachers understood but never excused anything. Every missed homework and late was sanctioned. I can remember having a wobble as I started my A Levels and thinking about University. It was difficult as I was working long hours and I knew that if I wanted to go to my preferred uni I would have to cut down on work and perhaps not work at all when I went to uni. I tried quitting saying that my live was too hard and that he was expecting too much of me. My teacher quite firmly told me that if I wanted to succeed I was probably going to have to spend at least the next ten years working harder than most of the people around me, not doing less . He was right , without support, role models , financial backing, appropriate discipline at home etc , it is harder work. Therefore if children from deprived backgrounds want to succeed they have to accept they need to do more than other people not less . It is shit, unfair but unfortunately the truth.
I have worked in a school with crap results, awful discipline and ineffective teachers which reassured itself that was doing a good job because it was in the top 10% nationally for CVA. This lead to a culture of the young people in their care being allowed to be half hearted . Sadly one of the reasons we did so well on value added was because the primary schools were doing such a bad job. Therefore they came to us, a school doing a little bit better than another shit school, and seemed to e making progress. As a teacher, I found myself being sucked into this culture. Spending more time doing "social work" than teaching . But many of these kids had social workers, they has counsellors etc, what they needed was the school to get tough and focus on academic learning. I am not saying that pastoral care does not matter, it does, but the balance has to be there.
My only way out of deprivation was through education, I knew that and yet I worked in a school that offered these kids everything but academic qualifications.
