Not that I really want to belabor the point, but often children did, and do, perform this service. As child labor laws changed the face of the work force, they became replaced by adults; here in the US. (Most often those of lesser education, or who were unable to obtain higher paying jobs due to discrimination; even though qualified.)
I do agree that the term "boy" has all too often been used as a pejorative towards adult minority males.
Indeed, we are all human beings. The sooner the last few of us get it through our thick skulls, the better.
