"Dissatisfied with the betterment schemes of socialists and others, with income tax measures, wage raising and bonuses, this author offers a solution in the single tax. Incidentally he has an interesting discussion of the theories of Marx, Georges Sorel, Spargo, Schwab, Scott Nearing, Nicolai and others" - The Booklist.
