And frankly, who can say which is worse. Mount Holyoke student Patty McCarthy, who took the class last year, told the AP she'd take it again. Someone in any form of work can feel exploited. It's all a state of mind. And there we have it.
Exploitation is a matter of feelings.
To be honest, I should be careful dismissing feelings as the key to exploitation. Feelings are relevant and historians risk hypocrisy by denying it outright. The children don't think they are being exploited. They think they're doing something that will get themselves and their families food and shelter. It's not just kids.
