You know what happiness is: 'Having a little more money than your colleagues.' And that's not so tough in academic life.
Paul SamuelsonOur ideal society finds it essential to put a rent on land as a way of maximizing the total consumption available to the society. ...Pure land rent is in the nature of a 'surplus' which can be taxed heavily without distorting production incentives or efficiency. A land value tax can be called 'the useful tax on measured land surplus'.
Paul Samuelson
