the only exploitation I see happening to children is the environmental indoctrination the kids are subjected to from prekindergarten upwards.
Hit the nail squarely on the head. Played sports growing up. I witnessed two incident involving a moronic parent (dads coaching baseball. Kids were on the team. Ugly scene).
I have read about overbearing parents who live through their children, and situations which involve moronic behavior, but the worse offender in the systematic exploitation of children is the public education systems.
