Almost a decade ago, I wrote a little book called The Politically Incorrect Guide to Socialism. When Regnery asked me to write the book, I was happy to do it but wondered whether a book on socialism, a brief conspectus of its grotesque failures, would be necessary or useful. I wondered why anybody would be interested. In the upcoming issue of National Review, I will have an essay on reading Karl Marx, and I do not have to worry about why people are interested. The world’s worst idea will not die. Source: Socialism: Why World’s Worst Idea Won’t Die | National Review
