In her fourth book Mayer draws on court records, extensive interviews, and many private archives to examine the growing political influence of extreme libertarians among the one percent, such as the Koch brothers, tracing their ideas about taxation and government regulation and their savvy use of lobbyists to further an agenda that advances their own interests at the expense of meaningful economic, environmental, and labor reform.Mayer is in conversation with James Bennet, the editor-in-chief of The Atlantic.
