"Socialist policy employs two methods to accomplish its purposes: the first aims directly at converting society to Socialism; the second aims only indirectly at this conversion by destroying the social order which is based on private ownership . . . . the second is the weapon of revolutionary Socialism" and "sabotage."
"Thus the beginning and end of the socialist policy, which has dominated the world for decades, is destruction . . . . Our whole life is so given over to destructionism that one can name hardly a field which it has not penetrated. 'Social' art preaches it, schools teach it, the churches disseminate it."
–Ludwig von Mises, Socialism (first published in 1922), pp. 424-425
