After the 1940s, Austrian economics can be divided into two schools of economic thought and the school "split" to some degree in the late 20th century. One camp of Austrians, exemplified by Mises, regards neoclassical methodology to be irredeemably flawed; the other camp, exemplified by Friedrich Hayek, accepts a large part of neoclassical methodology and is more accepting of government intervention in the economy. Henry Hazlitt wrote economics columns and editorials for a number of publications and wrote many books on the topic of Austrian economics from the 1930s to the 1980s. Hazlitt's thinking was influenced by Mises. His book "Economics in One Lesson" (1946) sold over a million copies and he is also known for "The Failure of the "New Economics"" (1959), a line-by-line critique of John Maynard Keynes's "General Theory".
