On yesterday's Oprah, Lisa Ling investigated the world of "freegans," people who live alternative lifestyles in order to limit their use of resources and their participation in the economy. Oprah sat with Madeline, a woman who earns a six-figure salary, but hasn't bought clothing in three years, and does her grocery shopping via organized trips of dumpster diving. The tactics of freegans can be a little outrageous, but so was the fact that Oprah was interviewing this anti-consumerist in a pair of Louboutin heels that look like they've never touched pavement.
