I'm looking into Italy and the economic miracle and was wondering how were they able to come back so fast and quickly after ww2?
Ah yes, the famed "Italian Economic Boom." How is it that Italy, which had undergone civil war and become a trampling ground for the Anglo-American Europe-wide pincer closing in on Nazi Germany, ended up being the 8th largest economy in the world by 1950?
Comparatively, Italy's work was probably harder than France and England's, but certainly not Germany's, an economy that would go on to become Europe's most robust. So we can say that Italy was not alone in facing challenges; indeed, in the immediate aftermath of the Second World War Italy's peers were also in an unfavorable economic state. Just think that the French industrial heartland in the northeast had seen some of the heaviest fighting on the Western Front, while Germany itself had ended the war bombed to smithereens, occupied, and divided. And Great Britain decided to deal with the aftermath of the war while trying to maintain a global empire: the perfect way to run your national budget into unsustainable territory! So let's keep in mind that Italy's recovery happened in a context where its closest neighbors, peers, partner economies, and economic competitors were all dealing with very similar problems.
Of course, the elephant in the room that needs to be immediately addressed is that all of Western Europe recovered more quickly thanks to the Marshall Plan. By 1948 the reconstructing European states had been buying so much American-made stuff that international money markets suffered a "Dollar Gut," pushing worried American legislators to take action. The problem was rather simple: the near total dependence on goods from the United States by the reconstructing Western European economies had crated a skyrocketing demand for US Dollars. This made important economic indicators, nominally balance of trade between the US and Europe, perilously skewered against Europe. And because everyone wanted dollars, their value appreciated. Like any good that becomes scarce, US dollars were becoming more expensive (which for a currency meant interest rates increased and prices of goods rose). In short, both US and European businesses and consumers began suffering.
The solution that US legislators came up with was to provide European governments with hard cash themselves. The European governments would then, under the oversight of the US' Economic Cooperation Administration (an ad hoc agency created to administer the plan) use the funds to buy the American goods they needed on behalf of local businesses. A liberal-minded economist might argue that the Marshall Plan was a panicked reaction by an American legislature and executive reading too much into economic indicators that, in time, would have corrected themselves. However, what cannot be argued is the immense goodwill and capacity to act that the Plan created, developing the political and economic capital necessary for the rapid creation of an integrated economic area that we generally refer to as "The West."
So the Marshall Plan didn't create the Italian Economic Boom; and it definetely isn't is the reason Germany is an industrial powerhouse today, or the Dutch are a again shipping power for that matter. Rather, the plan got the war-torn countries back on their feet. That's not to say participating European economies didn't benefit immensely from the Plan, because they most certainly did: especially the United Kingdom, which received some 26% of the funds allocated by the US Congress. But Italy, which received little over one-third of the amount that the United Kingdom had received, was particularly well-poised to distribute that which they had received. You see, major Italian industries were managed out of the Italian state-owned holding company, the Istituto per la Ricostruzione Industriale (or IRI) an agency of the Finance Ministry which had been created as a vehicle to conduct a series of nationalizations planned and carried out by the Fascist regime originally intended to counter the effects of the Great Depression and place the economy on a war footing. The IRI outright owned large companies active in vital strategic sectors, namely metalworking, shipbuilding, construction, and various kinds of transportation. The IRI also owned controlling stakes (but not total ownership) of strategic companies in sectors like banking, telecommunications, and even some firms active in mechanical engineering (beloved niche carmaker Alfa Romeo is a notable example). Thus while the Marshall Plan had intended to allocate funds to private corporations, through the IRI's ownership stakes the Italian government could influence private corporations vital to economic development. The presence of clear and open channels of communication between government and industry not only allowed for the quick and efficient impact of Uncle Sam's money, but private corporations could also be nudged into taking decisions based on considerations for the overall impact on the country's reconstruction, employment outcomes, and standard of living, even if the decisions acted to the detriment of corporate profits (indeed, an even faster postwar recovery took place following the nationalizations and collectivizations in the Eastern Block, a fact which played no small part in alarming political leaders to the west of the Iron Curtain and alimented the early phases of the Cold War).
The IRI's political control didn't entirely act to the detriment of corporate success either. In fact, while companies might have been pushed to prioritize employment outcomes over profitability, a direct line to the country's political system also gave companies a leg up in international trade (just think of how in the days of rotary phones and switchboards, a direct line from the boardroom to the Foreign Ministry must have been an invaluable advantage). Shrewd decisions, like the IRI's investments in iron production just in time to meet excess US demand during the Korean War, were clearly the consequences of explicit political tip-offs.
Another important point tied Italy's postwar "Boom" is that in the postwar era, the economy was in a position to complete its transition from a predominantly agricultural economy to an industrial one. In the fascist era, the policy of autarky had kept industrialization concentrated in the Turin-Milan-Genoa triangle without prospects for expansion or diversification: Italy's fragmented history had created a small but highly competitive region in the north west, while the rest of the country remained predominantly agricultural, with goods and services dominated by small local artisans and an even smaller class of professionals. It was only after the Second World War, when both the Marshall Plan and the budding European Integration Process demanded a rapid integration with the world economy, that Italian industry could spread and diversify and was no longer confined to national demand. Regions like Italy's northeast, which had lagged behind the rest of the more developed north, began developing the industrial and commercial components of its economy. The South too saw worker's wages rise, however its modernization and integration was slower; even during the "Boom," economic growth in Italy was very uneven.
Of course, the Economic Boom didn't come without drawbacks. While effort were made to locate some new public capital investments in the south, investment saw the greatest returns in the well-established industrial clusters in the north. Private capital investments both from within Italy and abroad wholeheartedly ignored the south. This catalyzed a dramatic phenomenon of internal migration, with the expanding industries in the north hiring southern workers who arrived in Turin and Milan by the trainload. And as southerners migrated to the north, a housing market boom quickly gave way to rampant speculation, with construction drastically modifying urban centers, leading to permanently changed landscapes with little concern for environmental impact or conservation of history.
Lastly, the largest impact was on the country's mindset and collective consciousness. Many people who had been born and raised on farms or small country towns had migrated to cities, and they now lived in modern apartment blocks. New roads, highways, and trains made the country "smaller" and more accessible. Expensive "Autarchic" technologies like clunky radios and television sets were now replaced with affordable units made with cheaper materials sourced from all over the world, contributing to the creation of a national pop culture. Both the large state-sponsored industrial conglomerates as well as smaller private companies competed to secure licenses to produce American goods for the Italian market, as well as producing goods for the wider world. Think of how shocking it must have been to see stuffy bourgeois cities become industrial hubs, while sleepy country towns became suburbs full of railway commuters. All this had an impact on the national psyche, and if on the one hand the newly liberated pop culture celebrated this newfound consumerist abundance, on the other hand the media also offered very self-referential examinations of the country's rapid transformation.
