Each of these policies might make sense on their own. But together they fundamentally shift the burden from parents and families to schools and the state. Undermining the norm of parental responsibility has very real consequences. A King’s College London study found that the proportion of Brits who think that it was important for children to learn obedience at home has fallen from 50 per cent in 1998 to just 11 per cent today – lower than all but four other countries. The underperformance of white working class students and the relative success of ethnic minority students is driven by one common cause: parents, and their attitudes to discipline and education.
Dubious survey- you could easily interpret that as meaning "do what everyone tells you unthinkingly". That would indeed not be great. Put it in terms of discipline at school, which is what he's doing here, and you'd doubtless get far more than 11%. Pathetic crude comparison between ethnic minorities and white working class too.
What has any of this got to do with free school meals anyway? You could be his very ideal of good parents and support universal free school meals, because you like the idea of the kids eating together and it will save you time from making sandwiches or whatever. But hey, it's a slippery slope if you're a libertarian.
