Great quote:
“… the state has been living on a revenue which was being produced in the private sphere for private purposes and had to be deflected from these purposes by political force. The theory which construes taxes on the analogy of club dues or of the purchase of the services of, say, a doctor only proves how far removed this part of the social sciences is from scientific habits of mind.”
–Joseph A Schumpeter, Capitalism, Socialism, and Democracy
