In reply to DaveHK:
I think Nickel and Dimed is well worth reading, I'm not sure why Straggler thought it was contrived, unless it's because she's a comfortably off writer posing as a menial worker in order to do the research - but that's the whole point of the book. It does a good job of describing just how hard life is for poor people in the richest country in the world.
I've also read Dancing in the Streets and Smile or Die, I'd recommend both.
