Switzerland has experienced strong economic growth in the late 19th century driven by industries like chemicals and precision engineering as well as the growth of tourism. It maintained neutrality in World Wars I and II, though controversially accepted gold from Nazi Germany. The Swiss economy continues to be highly developed and specialized in industries like banking, pharmaceuticals, and microtechnology with a highly skilled workforce. It has a stable economy and political system and remains prosperous today as a global leader in addressing environmental challenges through sustainable policies.
