It's quite interesting to appreciate that these issues were observed, and written about, some 2400 years ago. Times when ostensibly everything would have been practically alien. Yet it emphasizes that the thing that's really changing is not humanity, so much as it is technology. We're still trying, and failing, to deal with the exact same issues as we were thousands of years ago.
And mind you that's just the first time it was written down. I wouldn't doubt that these observations and issues long predate even Plato. Because I think one thing that's become clear is that he wasn't necessarily unimaginably brilliant so much as he was simply capable of objectively seeing the patterns in society and recording them. Though perhaps that is some form of brilliance in its own right.
