Query: The keys to a successful economy

Despite the erroneous claims of several Keynesian progressives, the supply side theory was actually a very successful policy that resulted in an average growth rate of 3.2 percent per year. That being said, this book is actually the first major attempt at expressing exactly what Supply Side Economics is. This attempt at profiling the dreams of the Supply Siders is something to admire however, the policies that were advocated in this book were not necessarily the policies that were in effect. Knowing this fact, all readers should read this book as a "treatise" on Supply Side Economics and not a vindication of the Reagan economic policies.
