Input: This book is not all that hard to understand. In simple terms, Laband and McClintock tell us that we waste a lot of money trying to avoid someone else wasting our money. It's not this fact that puts the reader so off guard. The fact that our society spends about four hundred billion dollars trying to influence two trillion dollars in government expenditures (about twenty percent of the total) shows what an inefficient mess our economy has become. This fact of wasted wealth should shock the reader. I couldn't believe it at first. The amount of research used is impressive and definitive. Though Laband and McClintock don't offer any serious solutions to the drain on the economy, this volume helps shape the continuing debate about wealth transfer.
Output:
Positive
