I am referencing a Guardian article that I read nearly a decade ago[0] but he wasn't the only one to have bemoaned the "youth".
With Socrates, him being sentenced to death while for "corrupting the youth" that's a pretty naive, and incomplete, explanation, if you were to dig a little deeper you'll find that the, probably, true reasons for Socrates' trial was political[1]. You forget that the "corruption of the youth" was bound with the accusation that Socrates was denying the gods and introducing new gods[2], not, as you imply, that he was a champion of the youths themselves. For me it's difficult to take everything we know about Socrates as true given the posthumous glow up that Plato gives us. This is partly Socrates' own fault for his, as we're told, ideas that writing things down would lead to forgetfulness. Ironic honestly.
I am tempted to discuss further about Socrates' trial, how most thought that he was going to going to get off due to his ability in rhetoric and hi, basically, not defending himself was pretty shocking in and of itself.
