A scout troop cannot exist without parent involvement. The national organization doesn't run them, each troop/pack is a self organizing group not only made up entirely of parent volunteers, but a rotating group as the children age out.

The fact that scouts has exists in this form for decades indicates this is a new problem.

Turns out Gen X and millennials are more disengaged than their boomer parents. At least in terms of the type of families who typically participate in scouts.
