Query: The Invisible Americans

I found Nickel and Dimed to be a good book. I read it for my ESL class and it helped me to improve my vocaburaly even though it was so hard at the beginning. It was amazing to realize how some Americans being Americans - as Barbara said in Nickel and Dimed - being white, English speakers, struggle in their own land with an unreasonable economic system. Barbara shows very well how poor workers are unable to live with their wages. The working class experience incredible and some times inhuman circumstances just to survive. Nickel and Dimed shows some of the terrible working conditions, and the result of them in most of those workers. It shows also how the same system is designed - in my opinion - not to help and assist these people.
