Ehrenreich brought to bear a subject of great importance -- America’s chronic under-employed. She did not do so with high prose or rich story telling. In fact, you will find yourself mincing her every approach and questioning some of her tinged conclusions. Still, you have to give her credit for throwing herself into the living realities of the clock-punching, shift-changing American minority. For 6 months, she went under cover attempted to live on a salary scratched from minimum wage jobs across the US. Her experiment in trying to live right at the poverty line failed, both for her and for the millions of real under-employed Americans. What tripped her up? short term: availability to cheap, safe housing (something I never considered) and long term: lack of medical coverage. Her short, quick book stays with you, because she manages to make you think long and hard about the invisible but real socioeconomic class system in America. It will make you think twice as you purchase fast food and shop at your favorite retailer. Where do these guys go at night? How do they feed their kids?
