While it's terribly fascinating for linguists it's generally understood that the languages and cultures within Switzerland are more related and generally homogeneous than when compared with for example asiatic language and culture.

Switzerland speaks languages from the Italic and Germanic clades of PIE [1]. That makes them about as dissimilar as Indo-Iranian and Slavic languages are from each of them.
Helvetia is a confederacy specifically because Switzerland has never been particularly homogenous. Homogeneity explains, in part, Nordic and Japanese success, though less and less the former in the modern era. It does not explain Switzerland’s.
Due to geography Swiss city states were able to maintain their independence and resist incorporation into larger principalities and subsequent empires. The Swiss militia that defended this was the basis for the American 2nd ammendment. Arguably it was the Swiss greater class homogeneity that explains their success.

Swiss territory has been part of, variously, the Roman Empire, various Germanic kingdoms, the Carolingian Empire, the HRE and Napoleonic France. Swiss independence was really only enshrined at the Congress of Vienna, I believe at the courtesy of Metternich. Of Austria-Hungary.

Yes, Switzerland was universally poor and started becoming wealthy with less inequality than other nations in the 1920s. (Note that in the 1910s like 15% of Switzerland was foreign born.)
The homogeneity pitch just doesn’t work for Switzerland.
Thank you. If the source is correct, and I have no reason to doubt it, the Founders were operating on bad information. Napoleon wasn't the "first successful foreign invasion" of the Confederation, unless we're being cute about how the HRE was organised.
