Or so goes the sixth-grade civics lesson. Against that, here’s Murray Rothbard:
The gravest crimes in the State’s lexicon are almost invariably not invasions of person and property, but dangers to its own contentment: for example, treason, desertion of a soldier to the enemy, failure to register for the draft, conspiracy to overthrow the government. Murder is pursued haphazardly unless the victim be a policeman, or Gott soll hüten, an assassinated Chief of State; failure to pay a private debt is, if anything, almost encouraged, but income tax evasion is punished with utmost severity; counterfeiting the State’s money is pursued far more relentlessly than forging private checks, etc. All this evidence demonstrates that the State is far more interested in preserving its own power than in defending the rights of private citizens.
