If becoming a teacher is the ultimate instrumental good, then we would all become teachers, then nothing would get done. Since that is obviously the worst of all worlds, it tells me that teachers do a good thing, but not the greatest thing. However, without teachers, few things would get done as everyone would reinvent the wheel. This is also, while not the worst scenario, it is far from the best. Thus, the best scenario seems to be that people should try to accomplish something, then go back and teach the next generation. The bonus is that these people will know how to get to the top. However, people who are good at getting things done are not necessarily the best teachers, and for the people that are... Perhaps, like we have today, those who are good at teaching and want to should teach, and those who want to produce should produce (and then later teach). The whole system relies on there being a good balance between the two. How to calculate the balance is very hard.
