Could you confirm that Sam Freedman, Policy Exchange’s head of education, has not been cloned at the Chicago Economics School from the DNA of Milton Friedman? (“Why teachers should learn to love the market”, March 6.)

Given that Milton’s ideas have just led to meltdown in the world financial systems, those who have noticed the link must feel something between amusement and foreboding. And what if Sam’s ideas become key features of our education system? Picture the scene in Freedman’s market: “Get yer luvverly O-levels. Beat the crunch and buy a bunch!”

It’s not just your final salary scheme that will go when those chums from Eton College run our education system. It’s your sanity they’re after, too.
