PPS I have had a chance to listen to the video, and in particular to the question and answer session of the final 30 minutes or so. Here are my comments on that, as posted on Bishop Hill (on the post linked to in the PS hat-tip):
'A Ph.D in education is "a valid marker" of left wing ideology in education these days. Anyone wishing to educate children rather than indoctrinate them and kibosh their chances in life should steer clear of any state validated educational qualification as the left has a stranglehold on content and delivery.'
