I've been thining about this some more, and I really think it's a matter of context and the fact that there is a religious element to it, for me.
When my daughter spent a week building houses for Habitat, I was proud and she got an award at school for it. If she were a Duggar, I'd feel that she was being used as cheap labor.
When my daughter came home the other night and said, "Mom, I'll make dinner" I was thrilled and proud that she could do it. If she were a Duggar, I'd think of her as a maid.
When my daughter wanted to wear something special the other day, she said, "Mom, don't take a shower yet - I'm doing laundry." If she were a Duggar, she'd be doing ten loads a day!!
All the same skills - just a matter of context. When my child does them, I feel like I've done something good as a parent - teaching her life skills, etc. When I watch the Duggars do it, I realize that for all the talking we do about how much we want our children to be self sufficient, there's a line that we feel the Duggars cross.
