Praxeology is a theoretical and systematic, not a historical, science. Its scope is human action as such, irrespective of all environmental, accident… - Ludwig von Mises

In fact, however, the supporters of the welfare state are utterly anti-social and intolerant zealots. For their ideology tacitly implies that the government will exactly execute what they themselves deem right and beneficial. They entirely disregard the possibility that there could arise disagreement with regard to the question of what is right and expedient and what is not. They advocate enlightened despotism, but they are convinced that the enlightened despot will in every detail comply with their own opinion concerning the measures to be adopted. They favour planning, but what they have in mind is exclusively their own plan, not those of other people. They want to exterminate all opponents, that is, all those who disagree with them. They are utterly intolerant and are not prepared to allow any discussion. Every advocate of the welfare state and of planning is a potential dictator. What he plans is to deprive all other men of all their rights, and to establish his own and his friends' unrestricted omnipotence. He refuses to convince his fellow-citizens. He prefers to "liquidate" them. He scorns the "bourgeois" society that worships law and legal procedure. He himself worships violence and bloodshed.

There were nowhere more docile disciples of Lenin, Trotsky and Stalin than the Nazis were.

The interventionists do not approach the study of economic matters with scientific disinterestedness. Most of them are driven by an envious resentment against those whose incomes are larger than their own. This bias makes it impossible for them to see things as they really are. For them the main thing is not to improve the conditions of the masses, but to harm the entrepreneurs and capitalists even if this policy victimizes the immense majority of the people.
