OP Ive just watched the Owen Jones RTS Lecture and thought it very reasonable - he was just asking for a wider range of voices on television; to include what used to be called "the respectable working class" rather than an unrepresentative portrayal of all working class people as disfunctional. Hardly revolutionary stuff.
Your comments on his accent are bizarre.. are you really suggesting he has changed it from that he would have had growing up and going to state school in Stockport? If so where is your evidence?
Your research on the role of grammar schools is also somewhat lacking.
For example, you need to consider the research of Adrian Elliott. In the TES he wrote:
"The argument that, in the past, selective education provided poor children with a ladder of opportunity compared with comprehensives today is equally dubious. The percentage of the population deemed working class by the Registrar General 50 years ago - 75 per cent - was three times that of today. So to accurately compare the academic achievement of working-class children today with those in the 1950s, the performance of the poorest third from then, those from unskilled and semi-skilled families, needs to be analysed. In reality, only a very small number went to grammar schools and many who did ended up with no, or few, qualifications.
A 1950s Ministry of Education study found that fewer than 0.3 per cent of pupils leaving with two A-levels were from the unskilled working class. Even among the top grammar school streams, a third from the poorest backgrounds left without an O-level. Many poorer children left even before taking public examinations."

I am actually a fan of the super-selective grammar schools with regard to the educating of academicly gifted and talented students. However, their role in social mobility is massively overstated. The real drivers to social mobility (IMHO) were quality apprenticeships, day release to technical college/polytechnics and grants.
On occasions I have found Owen Jones rather simplistic in his political analysis but Peter Hitchens is much, much worse
