If you're good you should be in charge of more people
Ummm, no. The skills required to be a good engineer are not the skills required to be a good manager of engineers. There's some overlap, sure, but you can be an outstanding engineer but have poor leadership skills, or be an amazing and revered leader but terrible at actually designing the stuff your people are working on.
You should be in charge of exactly as many people as you are good at being in charge of. That's unrelated to how good you are at being one of the workers.
