The first lesson in economics is: things are often not what they seem.
That’s a sentence in the first edition of Samuelson’s Principles. Justin Wolfers discusses the book here. Part of chapter one is on-line here. Use the search function. Here (search for "communism") Samuelson says that economics cannot pass judgment on whether American society will go the "revolutionary" path (toward communism) or the "evolutionary" path, or whether Russia indicates the "folly" or the "wisdom" of communism. Indeed things are not always what they seem. You can have lots of fun with the search service.
