Henry Simons and pre-World War libertarianism.

 I just posted this piece on a libertarian-affiliated U of Chicago website. Based on a 2013 article that I wrote concerning Henry Simons. It discusses the question of why a Friedrich Hayek-affiliated "classical liberal" would have supported both vigorous anti-monopoly enforcement and a high-rate progressive income tax - positions that are anathema to the likes of (say) a Richard Epstein or Milton Friedman (if he were still alive) today.
