This Land is Their Land is a collection of short articles, Ehrenreich's journalism. I was hoping to read a more systematic exposition on money and power in the USA. The following books may be better at providing a systematic exposition.
Erik Olin Wright & Joel Rogers. American Society: How It Really Works. New York: W. W. Norton & Company, 2010.
[Publisher; Google Books; Amazon.com.]
G. William Domhoff. Who Rules America? Challenges to Corporate and Class Dominance, sixth edition. McGraw-Hill, 2009.
[Publisher; Google Books; Amazon.com; Book webpage at author's website; Wikipedia on the Book.]
Thomas Ferguson. Golden Rule: The Investment Theory of Party Competition and the Logic of Money-Driven Political Systems. University of Chicago Press, 1995.

Michael Parenti. Democracy for the Few, ninth edition. Wadsworth Publishing, 2010.
[Publisher; Google Books; Amazon.com; Book webpage at MichaelParenti.org.]
Parenti himself recommends people aviod purchasing Democracy for the Few because of the exhorbitant price imposed on it by the publisher. You can get an earlier and used edition of Democracy for the Few for a very small price. Or you might instead consider this anthology of his writings:
