Market economy implies a self-regulating system of markets; in slightly more technical terms, it is an economy directed by market prices and nothing … - Karl Polanyi

The fascist solution of the impasse reached by liberal capitalism can be described as a reform of market economy achieved at the price of the extirpation of all democratic institutions, both in the industrial and the political realm. ... The appearance of such a movement in the industrial countries of the globe, and even in a number of only slightly industrialized ones, should never have been ascribed to local causes, national mentalities, or historical backgrounds as was so consistently done by contemporaries. Fascism had as little to do with the Great War as with the Versailles Treaty, with Junker militarism as with the Italian temperament. The movement appeared in defeated countries like Bulgaria and in victorious ones like Jugoslavia, in countries of Northern temperament like Finland and Norway and of Southern temperament like Italy and Spain, in countries of Aryan race like England, Ireland or Belgium and non-Aryan race like Japan, Hungary, or Palestine, in countries of Catholic traditions like Portugal and in Protestant ones like Holland, in soldierly communities like Prussia and civilian ones like Austria, in old cultures like France and new ones like the United States and the Latin-American countries. In fact, there was no type of background — of religious, cultural, or national tradition — that made a country immune to fascism, once the conditions for its emergence were given.

In effect, by far the greater part of trade flowed in such dispositional channels, while a much smaller part continued to proceed on transactional lines. Numerous devices ensured that no merging of the two should ensue.
Both equivalencies, which made gainless transactions possible, and rules of law, which organized riskless dispositions into a trading system, were a result of the dominance of redistributive forms of integration. But these did not operate in the ways of tyrannical administrative bureaucracy, as assumed by historians in the past. The absence, or at least the very subordinate role, of markets did not imply ponderous administrative methods tightly held in the hands of a central bureaucracy. On the contrary, gainless transactions and regulated dispositions, as legitimized by law, opened up, as we have seen, a sphere of personal freedom formerly unknown in the economic life of man.

By accident only, as we see, was European fascism in the 1920s connected with national and counterrevolutionary tendencies. It was a case of symbiosis between movements of independent origin, which reinforced one another and created the impression of essential similarity, while being actually unrelated.
In reality, the part played by fascism was determined by one factor: the condition of the market system.
During the period 1917–23 governments occasionally sought fascist help to restore law and order: no more was needed to set the market system going. Fascism remained undeveloped.
In the period 1924–29, when the restoration of the market system seemed ensured, fascism faded out as a political force altogether.
After 1930 market economy was in a general crisis. Within a few years fascism was a world power.
