Since the collapse of standards in state education there have been a disproportionate number of private school people succeeding in every walk of life.That includes Olympic gold medals. The British brag on more gold medals per capita than any other country in the recently finished games.
Perhaps the common schools have scaled back physical education and sport in order to save money, or to have more time for their students to fill in work sheets. But perhaps if the common schools would stop enabling mediocrity, they'd get less of it. And some of the people with means would enroll their children in those schools.
