The Politics of Food Supply, Concluding Thoughts.
I honestly cannot recommend this book highly enough to anyone who wants to have a thorough understanding of the history of U.S. food policy. That said, it's an academic work and not an easy read. But how could any exploration of such a complex subject be simple?
Potential readers should note that each chapter is written almost as a persuasive essay, taking numerous pages to refute the predominant thinking of a given nuance. For some readers (ahem, me) this is frustrating. But its ultimate effect is that when he gets to his real point, it's all the more clear.
In summary: want to know about subsidies and food surpluses? Read this book.
