Quickly found stuff from Wiki:
"The merger of four major firms into the
Vereinigte Stahlwerke (United Steel Works) in 1926 was modeled on the
U.S. Steel corporation in the U.S. The goal was to move beyond the limitations of the old cartel system by incorporating advances simultaneously inside a single corporation. The new company emphasized rationalization of management structures and modernization of the technology; it employed a multi-divisional structure and used return on investment as its measure of success.

Whereas Britain's share of world trade had declined between 1880 and 1913 from 38.2 per cent to 30.2 per cent, Germany's share had increased in the same period from 17.2 per cent to 26.6 per cent.
[53] Between 1890 and 1913 German exports tripled and by 1913 Germany's share of world manufacturing production was 14.8 per cent, ahead of Britain's 13.6 per cent.
[54] By 1913 American and German exports dominated the world steel market, as Britain slipped to third place.
[55] In 1914 German steel output was 17.6 million tons, larger than the combined output of Britain, France and Russia.
[54] Germany's coal production reached 277 million tons in 1914, not far behind Britain's 292 million tons and far ahead of Austria-Hungary's 47 million tons, France's 40 million tons and Russia's 36 million tons.

In machinery, iron and steel and other industries, German firms avoided cut-throat competition and instead relied on trade associations. Germany was a world leader because of its prevailing "corporatist mentality", its strong bureaucratic tradition, and the encouragement of the government. These associations regulated competition and allowed small firms to function in the shadow of much larger companies.

And I dont really see Americans in their 1920s mindset to open immigration more. I expect them to be even less reasonable in that.
