There's a crosswalk I pass on my way to work that always makes me think of this. An elementary school is located there, and every weekday morning there is a crossing guard (someone with lights and a hand sign who stops traffic to help kids cross) posted there. To be sure, I expect this person is indeed necessary, as traffic in that area is heavy and fast. But it strikes me as a dysfunctional that we need people dedicated just to allowing children to safely cross the street.
