There's a sense in which all taxes are antagonistic to free enterprise … and yet we need taxes. We have to recognize that we must not hope for a Utopia that is unattainable. I would like to see a great deal less government activity than we have now, but I do not believe that we can have a situation in which we don't need government at all. We do need to provide for certain essential government functions — the national defense function, the police function, preserving law and order, maintaining a judiciary. So the question is, which are the least bad taxes? In my opinion the least bad tax is the property tax on the unimproved value of land, the Henry George argument of many, many years ago.
