Daphne, I didn't mention school music tuition lessons .
Jen, is the problem not choice of food or a music lesson for all on low wages, it's children need iPads, iPhones etc. And yes only the more affluent can afford all this.
I doubt very much that the majority of children want to play a musical instrument, they don't want to spend an hour every night practising on the piano, flute, cello etc.
Not every child wants to join sports clubs, some children want to read for hours, some want to play football, some chat on their iPhones.
All children need to learn the three r's , not all need to play football, play the flute , join drama groups.
