There's also a Value Added Tax (VAT), which probably makes comparing the Swiss and US systems difficult: https://www.ch.ch/en/vat-rates-switzerland/
Hard to compare, but probably not grossly larger in Switzerland.
I wonder how property taxes compare.
Ah, here we go, taxation as a % of GDP: https://en.wikipedia.org/wiki/File:Tax-Revenues-As-GDP-Perce... Overall we, the US and Switzerland, track very well.
From https://en.wikipedia.org/wiki/Taxation_in_Switzerland which I'm just starting to look at.
