"[G]overnment can, instead of extending freedom, restrict freedom. And note ... that the 'can' quickly becomes 'will' the moment the holders of government power are left to their own devices. This is because of the corrupting influence of power, the natural tendency of men who possess some power to take unto themselves more power. The tendency leads eventually to the acquisition of all power - whether in the hands of one or many makes little difference to the freedom of those left on the outside."
