French teacher in Madrid doesn't know any French

I'm a bit unclear as to why there is so much fuss about the tale of Nadia Saffouri--efforts to reduce costs by optimising teaching resource usage are leading to similar situations right across the country, and restrictions on entry to the profession engineered by teaching unions and regionalist nationalists meant that incompetent teachers were already part of the deal for kids--but it does perhaps help to explain tolerance for poor language skills elsewhere.

(Why does anyone in Madrid or anywhere need to learn French, particularly with this kind of thing going on?)
