It certainly isn;t a choice, and whilst I'm no fan of MATs , I'm frankly horrified that someone that is a trustee thinks this.
You in fact prove me right with your point about PE, yes the DofE made PE a priority, and gave pots of money, that can't be spent elsewhere to fund PE. This doesn't mean its an individual school's choice to spend it over languages. It had to be spent on PE.
Most schools have a drama department because they can offer and fill GCSE drama ( not likely theatre studies) and which ever choice of A level they have. Since languages stopped being compulsory, that has become ever harder to do for most schools, meaning language teachers either double up on teaching 2nd languages, or are deployed to other subjects. As there are language teacher shortages they then migrate to other schools where they are used in faculty full time.
Do you provide for classes of 3? What do you take out instead.
Oh and that's before we get to equity. Why is Tom the History teacher paid exactly the same, and given exactly the same time to teach his A level class of 20, as Mike, who teaches Politics and who has a class of 5? Tom basically subsidises Mike because his subject is more popular.
