> What do you do when highly wealthy people buy property and then never sell? Tax them. Inefficient use of land is a good sign that the property tax is too low. If the government charged a property tax rate that roughly matched the property value increase, there would be no gain just by sitting on the property. You'd have to put the land to productive use to actually make a profit.
