Reply #1: I think much of that is people wanting power also.

[RandomThoughts]

So people that just want to move up do not look at their own limitations, and many times do things that falsely represent their own worth to get a new position, are not the best for that job. People that reluctantly move up because they are pulled by many people in society to do it, are not there for power, but for what is right.

Many promotions look for people that want that position most, and are willing to be bad to get it, the top gets not the most qualified, but the worst.

It may be a factor of what we use to decide if someone is best in a position. And people that got in power, by being picked by people in power, have a trend to pick the wrong people to promote. In that case randomness would be better.

The worst cases I have seen are self exclusive groups, where the people at top chose who should be in their group, by doing this the group moves more and more ideological until it collapses. In contrast democratic government uses the people on the bottom to chose the leaders.(if positions are not bought).
