Beatrix Potter: Social Commentary?

From the Wikipedia article on The Pie and the Patty Pan:

"The Tale of the Pie and the Patty-Pan and its two immediate predecessors The Tale of Two Bad Mice and The Tale of Mrs. Tiggy-Winkle are transitional works in Potter's life and literary career. All three books confront the meaning of domesticity, work, and social hierarchies while exhibiting an underlying restiveness with the unyielding strictures of Victorian domesticity, and a disengagement from the broad political and social concerns of her earlier books to the more narrow political and social concerns of working farmers and rural people." -Kutzer, M. Daphne (2003). Beatrix Potter: Writing in Code. London & New York: Routledge

Apparently, I need to read that book. Like many other children, I was fooled into thinking that Potter's adorable books were merely quirky animal stories. I always did like her tongue-in-cheek commentary about human behavior expressed through animal characters, but I can't say that I ascribed a lot of political and social stances to the books. I'm left wondering if Samuel Whiskers the Rat in "The Roly-Poly Pudding" represented the oppressive nature of the British 19th century class system now...geesh.
