By "preparing so many children for adult life and the world of work." do you mean telling most of those in schools that -
"We don't care that you can't afford to get any more formal education after you leave school, however much you are desperate to be a doctor, teacher, scientist, musician or graphic designer, because you were not born into the right family, living in the right area and working at a wellpaid career. If you work hard at stacking shelves in the supermatket, maybe after 10 years you will have enough saved to pay the £9,000 a year fees and your living expenses while you study. Meanwhile, don't get married and/or have any children to soak up those savings. However, we will make sure that someone's sex, ethnic origin, gender preferences, physical disabilities, and languages don't bar them from employment in the job of their choice."
