The ancient Greek model assumes a common end but in practice there were many conflicts demonstrating the ends were conflicting. The model itself is like the ideal form. Suggesting that western politics adopt this model when the current state of things opposes it is not necessarily an error.
5th C BC Greece was far from an ideal state, the collapse is visible here in rampant gambling. Take a civilization class, the first thing you learn is the West is overly confident and never expects change so change is imposed. While the Chinese expect change, and can pivot when things get bad. Continuity isn't a Western way.
