Ludwig Von Mises said this quote
“ How little one is justified in speaking in this connection of optimism and pessimism and how much the characterization of liberalism as optimistic aims at surrounding it with an unfavorable aura by bringing in extrascientific, emotional considerations is best shown by the fact that one can, with as much justice, call those people optimists who are convinced that the construction of a socialist or of an interventionist commonwealth would be practicable. Most of the writers who concern themselves with economic questions never miss an opportunity to heap senseless and childish abuse on the capitalist system and to praise in enthusiastic terms either socialism or inter ventionism, or even agrarian socialism and syndicalism, as excellent institutions. ”
