Earlier quoted context omitted.
Some might say that a good outcome is one where the people can freely make their own choices and accept the consequences. The plight of the British might serve as a cautionary tale informing the decisions of some other country, that's certainly a good thing in some sense. Democracy is not guaranteed to deliver prosperity or lead only to the correct decisions, yet it's the best system we have.
I often hear the refrain that, "democracy is the worst form of government except for all the other forms that have been tried". But how many forms have actually been tried? As far as I know, every country is either a democracy or an autocracy. Maybe it could be better phrased as, "Democracy is better than autocracy, and we think it's crazy to try anything else".
There is certainly in a lot of room for improvement in how we elect leaders and what powers we give them. But, I think the evidence overwhelmingly suggests that dispersed power is better than centralized power. Remember that humanity has in fact tried a lot of variations of democracy and government throughout history. None of us actually lives in a direct democracy today a la ancient Anthens, we live in republics.
