And I don't see any superior morality from privately educated folk.
And re: environment - our school is a frequent litter picker, the children have all sorts of nature clubs. Children actively encouraged to cycle to school, they have cycling tests at the end of the final year.
It is also very involved with fair trade - the children learn about supply chains and wages. They are very passionate about the farmers getting a fair amount of money for produce.
Another primary school has its own wind turbine!
I have also seen our local secondary school out litter picking in the surrounding streets.
I know thus is all anecdotal but I really, really don't recognise what this person is saying about state education.
I don't know what happens in the private sector - how are the children taught morality? I should imagine the strategies are informed by what is happening in the state sector. Otherwise perhaps they leave it up to the church.
