“Is that to say we are against Free Trade? No, we are for Free Trade, because by Free Trade all economical laws, with their most astounding contradictions, will act upon a larger scale, upon the territory of the whole earth; and because from the uniting of all these contradictions in a single group, where they will stand face to face, will result the struggle which will itself eventuate in the emancipation of the proletariat.”

Context: The importance of international trade for economic development cannot be overemphasized. But free trade is not the best path to economic development. Trade helps economic development only when the country employs a mixture of protection and open trade, constantly adjusting it according to its changing needs and capabilities. Trade is simply too important for economic development to be left to free trade economists.
