If you disagree, perhaps you could provide an alternate point of view? Why, for example, would less intelligent or competent people be easier to lead?
Let me give you an example: American military service tradition versus pre-Fall-of-the-Iron-Curtain Russian military service tradition.
American service personnel are generally encouraged in the pursuit of knowledge as relates to their career area, and are (generally) rewarded accordingly in the services. Someone who starts off at the very bottom tier of mechanics, for example, isn’t going to be told that his job is to change the oil on a jeep, period. He’ll be encouraged to learn about how engines work, why changing the oil is important, why tires being rotated regularly is important, how an internal-combustion engine works, and so on. If he demonstrates skill, maturity, and a willingness to learn, the Army/Navy/Marines will notice this, and will (again,
generally) offer him more opportunities to learn: classes he can take, the promise of promotion for competence, and so on. There’s a strong tradition of self-improvement in the US service, and in the US at large, a sort of “if you’re willing to pull yourself up by your bootstraps, the sky’s your limit, go for it” attitude.
In comparison, Russian submariners were not encouraged to know anything at all about the boats on which they served, or about anything beyond the very narrow scope of knowledge they needed in order to perform the particular task to which they were assigned. As a society, pre-fall Russia frowned on self-education: if the State determined that you were going to be a torpedo-loader, second class, then you’d better not have any ideas about how to load that torpedo better, faster, or more efficiently, much less about how to clear a clogged torpedo tube without blowing the ship up in the process. That wasn’t your job or your area, comrade–are you trying to take away Seaman Petrov’s job? And most Soviet enlisted submariners had a fairly minimal education at best, so even if they wanted to broaden their minds, they couldn’t–they simply hadn’t the background.
As a result, there were a lot of problems in the Russian military. For example, it happened that only their officers had the education or qualification to do even simple repairs on a ship. As a result, you could have only two or three people on board who were capable of, for example, doing anything from basic welding to diagnostic procedures on a nuclear reactor. There are some very nasty stories about the result of
that idea.
One more observation. There’s a longstanding tradition at a number of both US and Western European service academies. A young student, a would-be officer, is brought into a room and faces a panel of instructors. The instructors explain to him that he has a nice, big pile of equipment (ropes, pulleys, shovels and the like), a small unit of soldiers, commanded by an NCO sergeant, and the necessity of raising a flagpole. The point is for the would-be officer to solve that problem.
Option A would be for the officer to detail every single order he might give in the process of raising a flagpole: “Sergeant, do this. Corporal, do that. Etc.”
Option B–the correct option–is for the officer to give just one order. “Sergeant, I expect to see that flagpole raised by 1600 hours. Is that understood?”
Option A would be how the pre-Fall Soviet officer would have to handle the situation, and a massive waste of his time it would be, too. Option B presumes that the sergeant is reasonably intelligent and competent and could solve this simple exercise in engineering while his commanding officer sorts out something that requires his attention–be that a very large cup of coffee

, a stack of dispatches, or a battle strategy.
In short, having intelligent, well-educated people in your command make your job easier. A Russian officer would be threatened by intelligent, well-educated subordinates, while an American officer (ideally, at least) would welcome such subordinates because you can get a great deal more accomplished if you aren’t the chief cook, bottle-washer, commanding officer, and deck-welder all rolled into one.
