It's interesting that China's leadership is full of engineers and economists; as a whole they're probably far more qualified to do their jobs than the leadership of most Western countries. I think there's some truth to the idea that you can have qualified leaders or you can have elected leaders but you can't have both. Getting elected just doesn't translate into being the best candidate for the job. If positions in the private sector were filled by popular vote, industry would grind to a halt. I think if you honestly consider that as a though experiment, it's obvious that only a truly absurd and impractical amount of voter rationality would solve the inherent problem, which is just that it isn't a sensible way to fill vacancies.
