Or teach people to become leaders who can govern. What does it take to have a specialized field of studies to prepare people? The more the qualified experts compete each other in getting elected, the better.
While this is distasteful attitude on the surface, one thing it does do is make sure that at least a few of the elites grow up with a sense of nobles oblige and fosters a longer-term outlook. There are, of course, a host of disadvantages. So while I welcome the dismantlement of such attitudes among the elite, the problem is that nothing has risen to take its place. We sadly seem to be becoming more and more a "what's in it for me" society.
