You're not getting this at all. They are incomparable at so many levels:
1. There is a vast difference in population density, total population size, and total land mass, as discussed up thread.
2. Switzerland has a homogenous culture that has been extant for several hundred of years at a minimum and you could make an argument for over a thousand years. The western half of the US wasn't settled by Europeans until 150 years ago.
3. The U.S. has had both massive immigration from abroad as well as massive internal migration for the last 200 years. Aside from a few cities in the north east and south, there is essentially nowhere near the level of cultural continuity in the US that exists in most European countries.
4. Aside from the shared language, the cultural differences between various regions of the US are akin to the differences between Western, Southern, and Eastern Europe. Do Hungary and Germany agree on most political issues? Do Sweden and Italy?
5. The US culture is dominated by a settler/pioneer mentality because, up until about 50 years ago, if things weren't great wherever you were, you just uprooted yourself and moved West to find new opportunities. Nobody has been able to do this in Europe at a comparable scale for 1000+ years.
6. Switzerland does not have anywhere near the level of racial heterogeneity that the U.S. has. Not only does the US have a huge, underprivileged ethnic group that is descended from slaves, we have obtained a new huge underprivileged ethnic group in the last 60 years.
[edit] 7. Almost forgot to add: most US infrastructure, especially on the West Coast, was built during the automobile era.
So, no, they are not even remotely comparable.
