Henry George

Many people think Henry George called for communal ownership of land. They are mistaken–what George wanted is that when land is privately owned (which he readily accepted), its potential rent (so called economic rent) is shared. So I can’t answer you last question. The advantage is that the government gets the economic rent as its income instead of taxing the other production-based activities. All of these are burdens on national progress. By taxing land values, unused land becomes costly for its owner when held unused. Then land value tax encourages its proper use and at a lower cost, due to less competition for its availability, and it is beneficial to all but those who speculate in rising land values.
