In establishing this goodwill would also come greater opportunity to produce and export manufactured goods into the African interior that the British had been monopolizing.[18] Daniel De Leon theorized that while Germany had a strong population and one of the highest birth rates in Western Europe, (in 1900 there was 4.93 children per German woman, compared to the United Kingdom's 3.53, and France's 2.8[19]) this competitive edge was watered down due to mass emigration from rural areas. In De Leon's eyes Bismarck didn't want colonies for colonization's sake, but instead to foster economic growth; creating an industrial-capitalist class who could then create economic prosperity domestically, and keep would-be immigrants at home with a higher standard of living.[20] This was demonstrated through the creation of the Deutsche Ost-Afrika Linie in 1890, but also some years earlier by Bismarck's demands for credit from the Reichstag to establish steamship lines headed towards Asia, Africa, and Australia,[21] directly conjoining the German and foreign markets. While only the Australian Line passed through the Reichstag, Bismarck was vehement about bringing German unity at home through this colonial process.[22]
