From The Great Departure: Mass Migration from Eastern Europe and the Making of the Free World, by Tara Zahra (Norton, 2016), Kindle Loc. 2719-32:
Economic logic generally set the limits of humanitarian solidarity in postwar Europe. The employment contracts offered to refugees were often highly restrictive, designed to keep them in low-paid or undesirable jobs for as long as possible. Belgium’s “Operation Black Diamond” imported 32,000 DPs as miners, but required them to work a full two years in the mines before they were allowed to seek employment elsewhere. As of 1949, 8,000 had returned to refugee camps in Germany, unable to tolerate the harsh conditions. Other employment programs were similarly restrictive. Britain’s “Westward Ho!” program enabled 82,000 migrants from Eastern Europe to emigrate to the UK, but confined refugees to employment in mining, textiles, agriculture, or domestic service, rather than allowing them to move freely between jobs or professions.
The French government, with its ongoing anxieties regarding population growth, was initially among the most eager to recruit DP labor. The French military commander Pierre Koenig immediately recognized that East European DPs “represent a human and labor resource that we will have a high interest in using to the advantage of our country,” and he urged French authorities to recruit the best workers. In 1948, the French government even set up its own vocational training courses for refugees in the French zone of occupied Germany. Conditions for foreign workers in postwar France were notoriously poor, however, and that hampered recruitment efforts. Ultimately, the IRO resettled only 38,107 East European refugees in France between July 1, 1947, and December 1950. The bulk of refugees were headed to the New World. In the same period, the United States received 238,006 refugees, Israel 120,766, Australia 170,543, and Canada 94,115.
