| Ludwig von Mises | A capitalist world organized on liberal principles knows no separate economic zones. In such a world, the whole of the earths surface forms a single economic territory. | Liberalism | p. 113 | Protectionism |
| Ludwig von Mises | Economic nationalism is incompatible with durable peace. Yet economic nationalism is unavoidable where there is government interference with business. Protectionism is indispensable where there is no domestic free trade. Where there is government interference with business, free trade even in the short run would frustrate the aims sought by the various interventionist measures. | Human Action | p. 682; p. 686 | Protectionism |
| Ludwig von Mises | The philosophy of protectionism is a philosophy of war. The wars of our age are not at variance with popular economic doctrines; they are, on the contrary, the inescapable result of a consistent application of these doctrines. | Human Action | p. 683; p. 687 | Protectionism |
| Ludwig von Mises | Government does not have the power to encourage one branch of production except by curtailing other branches. It withdraws the factors of production from those branches in which the unhampered market would employ them and directs them into other branches. | Human Action | p. 737; p. 744 | Protectionism |
| Ludwig von Mises | The slogan Away with foreign goods! would lead us, if we accepted all its implications, to abolish the division of labor altogether. For the principle that makes the international division of labor seem advantageous is precisely the principle which recommends division of labor in any circumstances. | Socialism | p. 288 | Protectionism |
| Ludwig von Mises | People favor discrimination and privileges because they do not realize that they themselves are consumers and as such must foot the bill. In the case of protectionism, for example, they believe that only the foreigners against whom the import duties discriminate are hurt. It is true the foreigners are hurt, but not they alone: the consumers who must pay higher prices suffer with them. | Omnipotent Government | p. 183 | Protectionism |
| Ludwig von Mises | In the long run there cannot be such a thing as moderate protectionism. If people regard imports as an injury, they will not stop anywhere on the way toward autarky. Why tolerate an evil if there seems to be a way to get rid of it? | Omnipotent Government | p. 250 | Protectionism |
| Ludwig von Mises | From the purely economic point of view nothing speaks against free trade and everything against protectionism. | Nation, State, and Economy | p. 64 | Protectionism |
| Ludwig von Mises | Hunger and anarchythat is the result of the protectionist policy. | Nation, State, and Economy | p. 75 | Protectionism |
| Ludwig von Mises | Every restriction of trade creates vested interests that are from then onward opposed to its removal. | The Theory of Money and Credit | p. 288 | Protectionism |
