There is a strong word of caution in that statement. I believe there is a great bit of truth to understand but I think many may be blinded by the moment, or by their specific candidate/s to understand the broader implications. But this is largely due the nature of our minds.
Regardless of what side you are on, be careful what you wish for. We can’t have it both ways. The masses shouldn’t be who elect our leaders, but at the same time, we want the people to feel connected and empowered toward the leaders. I have no idea what the ideal solution is, but to believe that the masses will make the right decision is lunacy. It’s only a matter of time and circumstance that will lead us to civil-war.
Anyway, Socrates words ring true to me, I think true democracies are doomed to fail. But perhaps the broader more important question: Are all governments doomed to failure? If that is the case then it’s a question of lifespan.
