Pretty much every company I’ve been in or know of values a vertical trajectory instead of a horizontal one for its employees i.e becoming a manager nearly always means a faster salary progression than becoming an expert in one or multiple fields.
Why is expertise valued less?


That is true, but you can become an expert in multiple things. For example you become an expert brick layer and then you become an expert plumber, and so on. Or in a knowledge based company, you become an expert payroll accountant, then an expert tax accountant, then an expert revenue accountant, etc.
So people value knowing where to go more than being able to get there? Is this the gist of it? If so, why? I don’t understand why one is more important than the other. You can have the best plan on the planet, but if you don’t have the people to get you there quickly, safely, and in top shape, that plan is just that, a plan.
A good plan with average people can still succeed. You’ve built a mediocre house. It has some value.
A bad plan with the best people will fail. You’ve built the wrong house. It’s worthless.
That’s the thing with management, they have impact beyond themselves.
