I'm just going to re-iterate the recommendation to read this book. Although it's periodically mentioned on HN, anyone who hasn't read it, you won't regret it. I would describe it as nothing less than the most eloquent and reasoned summary of the devastatingly unfortunate wholesale misapplication of human endeavor in modern times... bar none... which incidentally lies at close to the root of many of the world's problems. In short: we've been flying with blinkers: Graeber explains precisely how and why.
