I see your point, Meadow. As I watch her manipulate folks (mostly men) to get what she wants, she almost seems to grow horns... However, she was a product of her time. A woman's lot in life depended upon how well she could manipulate men. Owning her own property and business was unheard of (though Scarlett managed to do both, didn't she?) Girl children were taught very differently from boy children - and it remains so today in many instances... They learned to cook, clean, sew and manage their homes (and their men) as well as manage their help and manipulate their social circle. Each girl child (especially in Scarlett's "class") was the center of her own universe. She may not have had a lot of control - but what she had - she manipulated to get. I did feel bad about Scarlett's treatment of Melanie (who was cut from a whole different cloth than Scarlett...). I grew up in the South and it has changed very much, of course, but girl children (I believe) are taught to be aware of tactics like Scarlett's. Sayings like - "A true Southern Belle can tell you to go to hell in such a way that it is 30 minutes or longer before you figure it out" When I read the book, I try to picture the time period it portrays. I may be way off base, here - but I don't think so...
Each person will judge the content of a book based on their life experience. Every book will read differently to each person who reads it - no matter what the author intended. I don't see Scarlett tossing around a lot of "the milk of human kindness" but, she was smart, feisty, determined and close to fearless -
