Although I find the diversity of opinons on every issue to be important, and in that way supported this book, I did dislike the fact that Hanson used supposed "proof" to support his theory in the form of numbers and data and yet mysteriously did not footnote any of it. I shall not in any way accuse him of making up this data, but I can't help but wonder: is his data coming from perhaps only a similarly like-minded source and not from official documents? Why else would he not have cited his sources? I can't help but feel that it is perhaps it is a bit too xenophobic towards a group of hard-working people without whom, I must say, the booming economy of California would not exist, at least not to this extent. I doubt that any reasonable middle-class citizen would prefer to pay $10 for a half pound of grapes than continue to open their doors (more or less, less really being the operative word here) to their friendly neighbors to the South.
