This article in The New Yorker is a long read. It will introduce you to a subject about which you are probably unfamiliar. It describes the world of Paul Singer, a billionaire investor. He is relevant to this blog because he is not only a billionaire but he gives generously to charter schools and Republican causes. Charter schools are the favorite hobby of hedge fund managers, equity investors, and Wall Street. These groups make large campaign contributions to influential politicians. They are underwriting the destruction of public education. They don’t know much about education, but they know markets. It is important for you to understand their thinking.
