The message from John Cartmell contains these words:
Think? You're just spouting total bollocks.
But just for the record 'vast bulk' implies a much greater ratio than two to one even if I give you the benefit of the doubt and assume you meant your comparisons to be taken on a pupil to pupil ratio.
And as for the the 2/1 ratio if that was the case where did the money go? It certainly didn't all go in teachers salaries and the overheads for most academic subjects were considerably less than for practical subjects.
In my neck of the wood it was the secondary modern that got the new buildings (including science labs) on a greenfield site, the new equipment and the better facilities. And the building vacated (it went on to become a primary school and is now a magistrates court) was on a par with that of the local grammar. The SM taught (among other things) metalwork, woodwork, domestic science (so could have been drivels alma mater) and even seamanship. The ersatz local grammar school taught none of those.
