Thank you for your fascinating detour into political philosophy.
To fit in with what you are saying the US has been designated a flawed democracy by the Economists Democracy Index as well as by others indicating that the USA is nowhere near what should be considered a democratic gold standard. What is though? All are flawed. Arguably the Scandinavian countries, Germany and NZ are amongst the best but even Germany has shown its weaknesses towards Putin in recent years.
On democratic philosophy what is the most Ora focal system? It’s the system which allows human nature to continue. Capitalism is so successful because it allowed people to be greedy and ego driven for example.
Any future system would need to be similar. If the state and the economy are to be separated it will never happen if it’s at the expense of the rich and powerful. If however a system can exists which allows them to stay rich and powerful while also helping the people, it might succeed.
Thanks again for your thoughts.
