Responding to the Edit about land: Well actually wealth tax is often used as an idea to control property prices. If you own $10 million in land. That land makes you no money, you'd have to work out how to make money from the land or diversify to make a minimum return that covers the tax. The consequence of which is land/property becomes a less desirable investment compared to say investing in businesses unless that land actually makes a return. Theirs pros and cons and a lot of discussion on wealth tax etc. But taxing income also has pros and cons. The question is do you want tax to tax evenly across peoples wealth, or do you want it to tax evenly across income? or some mixture of both?
