Does anybody here know of a good modern book about land value tax or Georgist economics in general? Any (constructive) opinions would also be welcome.
George's essential political idea was that society is not a struggle between labor (workers) and capital (entrepreneurs, investors, landowners, etc), but between rentiers - paradigmatically landlowners, but in neo-Georgist thought all "owners" - and the "productive" classes (labor and entrepreneurial capital). For George, the general interest can always be identified with capital accumulation. Rentiers stand in the way of capital accumulation, and thus in the way of the general interest.
Many software developers feel the line between entrepreneurial capital and highly remunerated wage work is quite blurry because, for at least two decades, they have seen a significant amount of upward and downward mobility. Who doesn't know someone who started a "lifestyle business", retired early, or cashed out some stock options and played the VC game a bit? Combine this with the obvious dysfunctionality of the Bay Area housing market, VC excess, etc. and Georgism seems entirely natural.
The difficult questions for the neo-Georgists include: Can capital accumulation really be identified with welfare? Given how stagnant labor productivity enhancing technological development has been for two decades, can we really assume institutional changes will boost it? If they can't, doesn't this make the normative questions all the more difficult?
