Lacey gives a persuasive argument for a more open immigration policy in the United States. With a notable lack of bureaucratic jargon, he explores America's evolving attitude toward immigrants, referring extensively to the work of experts in politics and economics to illuminate myths and to demonstrate that mass migration has always been good for the U. S. economy. Although he does not include a bibliography, he does give the authors and titles of pertinent monographs within his text. This book would be an excellent starting point for students researching the topic because it does not assume a great deal of background knowledge.
