The question was whether there were any pre-1930s economists in favor of the "pure free market." I don't see how my pointing out Mises's criticisms of government intervention into the market process is a "loaded way to refer just to actions supporting labor and the poor against property and the rich." In the book I referenced, Mises defines(p. 20)interventionism as "a limited order by a social authority forcing the owners of the means of production and entrepreneurs to employ their means in a different manner than they otherwise would." The first topic he takes up after that is tariffs. The next is price control. Samuel Bostaph
