One of the attractions of going to Calabria, for me, was to continue in a new location my research on labour supplies. I had already seen in Rhodesia how, when the Africans were fully proletarianized—or, more precisely, when they became conscious that they were now fully proletarianized—this led to struggles to get a living wage in the urban areas. In other words, the fiction that ‘We are single males, our families continue to live peasant lives in the countryside’, cannot hold once they actually have to live in the cities. I had pointed this out in ‘Labour Supplies in Historical Perspective’. It came into clearer focus in Italy, because there was this puzzle: migrants from the South were brought into the northern industrial regions as scabs, in the 1950s and early 1960s. But from the 1960s, and especially the late 1960s, they were transformed into class-struggle vanguards, which is a typical experience of migrants. When I set up a research working group in Calabria, I got them to read the social anthropologists on Africa, particularly on migration, and then we did an analysis of the labour supply from Calabria. The questions were: what was creating the conditions for this migration? And what were its limits—given that, at a certain point, instead of creating a docile labour force that could be used to undermine the bargaining power of the northern working class, the migrants themselves became the militant vanguard?

Two things emerged from the research. First, capitalist development does not necessarily rely on full proletarianization. On the one hand, long-distance labour migration was occurring from places where no dispossession was taking place; where there were even possibilities for the migrants to buy land from the landlords. This was related to the local system of primogeniture, whereby only the eldest son inherited the land. Traditionally, younger sons ended up joining the Church or the army, until large-scale, long-distance migrations provided an increasingly important alternative way to earn the money necessary to buy land back home and set up their own farms. On the other hand, in the really poor areas, where labour was fully proletarianized, they usually could not afford to migrate at all. The only way in which they could do so was, for example, when the Brazilians abolished slavery in 1888 and needed a substitute cheap labour force. They recruited workers from these deeply impoverished areas of Southern Italy, paid their fares and resettled them in Brazil, to replace the emancipated slaves. These are very different patterns of migration. But generally speaking, it is not the very poor who migrate; it is necessary to have some means and connections in order to do so.
