The level of this debate has plummeted considerably. Latin alone does not a good education make. Public schools do not get good results and churn out students who get into top universities and top jobs because they teach Latin. Nor do they get good results because they have better teachers or better teaching. They get better results because they SELECT. How can anyone not understand this?
It's the same to a lesser extent with any school (state or private) that selects even if the selection is less obvious i.e. by 'musical aptitude' or faith or whatever.
FWIW there would not be many people who would object to any school, state or independent, offering Latin to its pupils. However making Latin compulsory for a whole school in London as part of a belief that this will automatically transform results and opportunities is utterly fatuous.
The notion that if only state schools would teach Latin and make the buggers have the right hair cuts then they too could get into Oxbridge and be running the country (forget about the centuries of entrenched snobbery and social inequality) merely validates and perpetuates the snobbery and social inequality.
I find the stupidity (because that is all it is) of those people who hold up schools taking only the most privileged children with supportive parents on good incomes with good educational backgrounds themselves (and most of the top performing state schools come into this category if you look at the numbers of children on FSM and SEN) as models of good practice and expertise to those schools in urban, deprived environments which are genuinely inclusive absolutely extraordinary.
Really, so much for your own education and intelligence, if you can't see the flaws in these arguments.
