When were you in Switzerland? If long time ago then you might not be aware that the Swiss franc has gone up relative to US dollar close to 30% (1.23 CHF/USD 10 years ago, 0.91 CHF/USD today).
About 6 years ago, so the change in exchange rates hasn't been that dramatic. Though I did make a bit of a profit by leaving a good chunk of my excess earnings in my Swiss account (there was a good chance I'd go back), until the Feds forced UBS to close US-related accounts.
Some random average prices in Basel for your information below. Not the cheapest option possible, but comparable to something like Safeway in US.
Note that some of those don't apply to someone choosing an outdoor/Mustachian lifestyle. E.G.
Beer (0.5 l) 7.5$ (in a pub) - Don't go to pubs much, if at all. I have no idea what the price of beer is in a US pub.
Rice 2$/kg - about the same in US, if you don't buy from bulk bins.
White bread 2.6$/500 g - maybe the same, it can vary by a factor of 2-3 depending on type & quality. I don't buy typical US white bread (the pre-sliced "Wonder Bread" sort), but might sometimes spend $4+ for an artisan loaf from Whole Foods or similar.
Apples 4$/kg - could be about the same, depending on variety.
Monthly local traffic pass 80$ - this is for bus &c? No equivalent most places in the US.
Very cheap eating out 25$ (ca 15$ at McDonalds)
Midrange restaurant for two (no wine) 80$ - If Mustachian, not relevant :-)
Return train ticket from Basel to Zurich (half price) 40$ - Again, no US equivalent most places/
Gas 2$/l (ca 7.5$/gallon) - Not relevant to Mustachian, as it's perfectly possible to live without a car (at least in Lausanne area).
