"A basic principle of economics holds that it is highly efficient to tax rents because such taxes don’t cause any distortions. A tax on land rents doesn’t make the land go away. Indeed, the great nineteenth-century progressive Henry George argued that government should rely solely on such a tax. Today, of course, we realize that rents can take many forms – they can be collected not just on land, but on the value of natural resources like oil, gas, minerals, and coal. There are other sources of rents, such as those derived from the exercise of monopoly power. A stiff tax on all such rents would not only reduce inequality but also reduce incentives to engage in the kind of rent-seeking activities that distort our economy and our democracy." Joseph E. Stiglitz, The Price of Inequality (2012: 212-213)
