Something else... in terms of skills, when I was at my comprehensive (the horror!) we had a screen printing workshop, pottery kiln and dedicated pottery teacher, photography studio, drama studio with full lighting/sound system, wood/metalwork shop and a mini farm.
I had free private lessons in 2 instruments, was loaned the use of an oboe as we couldn't afford one etc
I'm not sure how much of this access to the arts is available to working class children anymore. And yet these skills enrich your life, especially if you have a routine or stressful job.
Surely access to the arts and to sport is one way to build children's confidence and these 'soft skills' it also helps children from different backgrounds mix on a level playing field.
