The happiest nations have been shown to be those with the smallest gap between the richest and the poorest. Britain does badly in that respect.
I agree, Cathy, he seems to be talking sense.
I was always aware when teaching bottom streams in inner city comprehensive schools that there was only so much I could achieve in the school day, but I was able to form a bond with quite a few mothers (fathers were not much in evidence, or they did not come to parents' nights). I am afraid I did tell lies, or at least I stressed all the positive aspects of their child, and 'forgot' a lot of bad behaviour.
Their children tended to be very well behaved for me for a time after their astounded parents had told them how pleased they were with their improved report.
I believe that some teachers set their aims too low for certain children and it becomes a self-fulfilling prophecy.
