The enemy is the State, and all who support and benefit from it at the expense of the rest of us.

All its labyrinthine schemes can be understood via the ancient question succinctly posed by the Romans:

"It is the state that is robbing all classes, rich and poor, black and white, worker and businessman alike; it is the state that is ripping us all off; it is the state that is the common enemy of mankind." ~ Murray Rothbard
