"In Charge" implies a management issue. Leading a troop and leading people are two different animals that often get confused as the same thing when in fact they are not.
I have seen many times where PL's TG's DC's show more leadership than SPL's, and even authoritarian SM's.
Out of all the Eagle speeches at ECOH's I have heard over the course of the past 35+ years, only one Eagle ever thanked his fellow scouts for making it possible for him to lead. We hear the thanks go to parents, SM's, ASM's, some particular mentor, or whatever, but never for the faithful followers that would do anything and everything to have participated in helping this boy be a Real Eagle.
DC's are not "in charge of" anything, but a good DC will lead his den in the cross-over into scouts.
TG's are not "in charge of" anything, but the new boys hang on their every word.
PL's are not "in charge of" anything, but when one of their patrol members is a bit bummed out about not being at home, will sit by the fire until the boy quiets down and heads for bed.
GrubMasters are not "in charge of" anything, don't even get POR credit, but spend a lot of extra time coming up with nice things to eat, learns new recipes, holds out the mushrooms for one boy who doesn't like them, watches labels for peanut oils, and does the shopping, teaching others how to put together menus for advancement, and a whole host of other duties.
I am super glad my boys never learn how to be "in charge of" anything. They are too busy learning how to be great leaders.
