Well yes... and so what? It’s not comparing the lot of educated CHILDREN, but children OF THE EDUCATED. Education does not pass to heirs via DNA. Surprised? (And also as long as the education is not MIS-education, their societies will be better and the children WILL benefit from that.)
Thing is in the old days a picked on scrawny kid might get a lick or two in. Now with growth hormones in milk some 15 year olds have the body of a full grown man. Is closer to a prison beat down.
A quote from Tolstoy may not be a good example. He was strongly influenced by the guy who more than any other of his time screwed around with how children are viewed.
“Rousseaus critique of modern civilization and his belief in the inherent
goodness of untutored nature left a deep imprint on Tolstoys art and
thought. His celebration of the noble savage in his fiction, from The
Cossacks (1863) to Hadji-Murat (1904), as well as much of his later
assault against the injustices of the state, the institution of serfdom, the
Russian Orthodox Church, modern medicine, education, marriage, and
sexual mores all derive, in part, from Rousseaus intellectual influence.”
