Seems the most effective approach to retaining power is to never actually achieve your stated aims, but to keep talking about them.
Yes, was talking to my friend yesterday about why so many leaders are apparently so incompetent. Well, that's if we assume their aim is to achieve their stated aims, if it's actually just to talk about them while staying in power then maybe they are actually not so incompetent on their own terms.
There is also the issue that they are normally selected by either voting or some kind of horse-trading power struggle type thing. In each case it's not obvious to me why there is any particular reason why the person who is good at winning such contests should be good at running a country.
There are two explanations, the first cynical, the second just depressing.
