This is a powerful manifestation of implied bias. This and the whole preceding sentence make it all seem weirdly propaganda-y. Like trying to say "no government will succeed forever" and yet also the doublethink that democracy is special, despite autocratic rule dominating human history. For example, consider the opposite and whether it sounds "normal":
> Autocracy isn't guaranteed to succeed, like any form of governance. Democratic regimes however are destined to fail at some point.
Edit: I am pro-democracy but have no delusions that it is free (as in beer), natural (as in humans will naturally tend towards it), nor easy (as in effort is required to maintain it). It's none of the above.
Additionally, democracies excel in freedom, wealth, safety and stability against any other form of government in today's world. And then some.
Let me take a guess: You are living in a first world country and you are a bit unsatisfied with your life?
If the answer is yes, I extracted that solely from bias. Helpful, isn't it?
I'm not sure what the line about "helpfulness" is talking about (bias or democracy), thanks to the ambiguities of the English language.
Democracy is competing interest groups. Just that they're supposed to compete nonviolently for the favour of public opinion.
Iraq should be a good lesson, though. Far too little effort has gone into understanding and explaining what was intended and how it failed, including what the weaknesses of good intent were. To me, it looks like the problem was trying to airdrop "democracy" consisting only of voting, without much thought given to parties, media, class structure, ethnic division, and economic crisis.
But making a statement about the viability of democracy because Iraq struggled to form a stable government is complete nonsense.
This could apply to a surprisingly large number of Western countries in the 20th century. Or the whole US "voter suppression" debate.
But the Roman empire lasted fifteen hundred years, while the republic only lasted five hundred -- as a classic example.
