Ha! That's what you get for scoffing, Rainstop. I dare you to have a good time!
I loved the series too, and also thought it was groundbreaking - not least because it portrayed the lives of single women as fun and cool, rather than pathetic.
Conspicuous consumption was a big part of it, and I think it was addressed sometimes - Carrie, for example, had a huge collection of designer clothes and shoes, but couldn't afford to buy her apartment. Partly the point was that these were single women, they earned their own money and they could spend it on whatever the hell they wanted - as in one of my favourite episodes 'A Woman's Right to Shoes'.
Sheila, have you read Ariel Levy's
Female Chauvinist Pigs - Women & the Rise of Raunch Culture? She discusses the consumerism in SATC, as well as other aspects of the show. It's a great book anyway, one I'd heartily recommend.
