I take issue with the final sentence in the below New York Times op-ed. Not only did Georgism account for greed, it was essentially designed as a system to dampen or ameliorate greed, which I would think means the desire (and collection) of more wealth than one deserves.
Greed, in economics, is almost synonymous with rent-seeking. Georgism neutralizes rent seeking (provided new forms of rent are identified and taxed as the greedy invent them). As long as assessment is accurate, greed becomes very difficult to act upon.
