The above quotation was from Socrates.
No, it's paraphrase of a quote from Aristrophanes' comedic play The Clouds altered to sound more like how an adult of the mid 20th century adult would complain about the youth of the 1950s, which is when the quote in that form actually dates to.
The actual portion from the play reads:
I will, therefore, describe the ancient system of education, how it was ordered, when I flourished in the advocacy of justice, and temperance was the fashion. In the first place it was incumbent that no one should hear the voice of a boy uttering a syllable; and next, that those from the same quarter of the town should march in good order through the streets to the school of the harp-master, naked, and in a body, even if it were to snow as thick as meal. Then again, their master would teach them, not sitting cross-legged, to learn by rote a song, either “pallada persepolin deinan” or “teleporon ti boama” raising to a higher pitch the harmony which our fathers transmitted to us. But if any of them were to play the buffoon, or to turn any quavers, like these difficult turns the present artists make after the manner of Phrynis, he used to be thrashed, being beaten with many blows, as banishing the Muses. And it behooved the boys, while sitting in the school of the Gymnastic-master, to cover the thigh, so that they might exhibit nothing indecent to those outside; then again, after rising from the ground, to sweep the sand together, and to take care not to leave an impression of the person for their lovers. And no boy used in those days to anoint himself below the navel; so that their bodies wore the appearance of blooming health. Nor used he to go to his lover, having made up his voice in an effeminate tone, prostituting himself with his eyes. Nor used it to be allowed when one was dining to take the head of the radish, or to snatch from their seniors dill or parsley, or to eat fish, or to giggle, or to keep the legs crossed.
The speech is actually given by the character named "Right" who is engaged in a debate with a parody of Socrates named "Wrong".
