After the rise of Hitler, German colonization in South America is no longer espoused by Ross
In editions of his South America book published after 1933, Ross greatly changes his stance on the question of German emigration to South America.
In the original 1922 publication of his book, Südamerika, die aufsteigende Welt, Ross described a German population displaced by war and contemplating overseas emigration. In future editions of the book, however, Ross changed the destination and set his description in a different idiom. In the 1941 edition, for example, published after Germany had advanced into large stretches of Eastern Europe, Ross suggests that Germans’ sights have now shifted to the new periphery of expanded German space: “Since Hitler’s takeover of power and particularly since the establishment of the Greater German Reich, the German people are no longer interested [in settling in Argentina], because now they have space and colonization possibilities in their own land, and Germans no longer need to be the cultural fertilizer (Kulturdünger) for foreign peoples”.
