You can read this exact criticism of democracy in „Athenaion Politeia“, (The Old Oligarch), 5th century BCE. There is nothing new under the sun.

To ignore scale differences here is to negate what could have been a great comment into a miss.

Scale is an important aspect. If something doesn’t work in a greek city state, it certainly won’t work in anything larger.
