Kostolany, spurred by his successful investment in Germany after World War II, held a deep respect for "the inherent qualities and capabilities of the German people", which, according to him, would consequently lead Germany to a new economic boom (see Wirtschaftswunder), after the German economy absorbed the shock of reunification.
Kostolany was a critic of the gold standard, the monetary system that fixes exchange rates to the price of gold, since he believed that whenever it was used, it suppressed economic growth and led to cyclical crises.
