Democracy, in and of itself, is neither a good nor bad thing
If the people of a nation are virtuous then democracy, no matter how perfectly it's done, will produce a virtuous government in general, all else being equal.
Because virtuous government activity will now be getting done in the name of the people.
Likewise, if the people in general lie, are corrupt, selfish and ignorant, the same system will deliver corrupt, selfish, ignorant government.
More seriously still, the more perfect the voting system and the easier it is to vote, the more intensely and with a stronger mandate will that government conduct itself on the basis it was elected by the kind of people above.
So democracy, in and of itself, is neither a good nor bad way to select government. It is what the people make of it...
"Under all forms of government the ultimate power lies with the masses. It is not kings nor aristocracies, nor landowners nor capitalists, that anywhere really enslave the people — it is their own ignorance. Most clear is this where governments rest on universal suffrage."
What did you make of it when you cast your vote in the UK's EU referendum recently, either as a leaver or remainer? Did you vote to leave or remain based on good virtue and the love of our children. Or your personal selfish interests, ignorance, irrational fears and hysteria?
Some nations punish their people for not casting their vote. Quite a neurosis given this takes away the very rights democracy gives by implication. Australia is such a nation, and they will soon be electing a new leader.
Here's the ozzie catch: If the people are forced to vote in a democratic election under pain of fines or other legalised punishment AND if the candidates are all known to be lying or corrupt, (as with the EU referendum in the UK) then what does that make of the people of a nation?
You, as a voter, will be implicitly supporting the lies and corruption unless you abstain. For the lies and corruption will now be getting done in your name. And you will have done this deliberately by free will.
Might this be why you will never find a "none of the above" box on the ballot paper of every democratic election? Everyone would abstain, of course.
Spend some time thinking about this with great care.
