I currently live in Switzerland (more precisely in Basel), and so far I like it very much. The cost of living is high, but the wages are even higher. As a PhD student, I earn 3100 CHF net/month (around 3400 $) and this is considered a very low wage, below what even an unskilled worker can earn. My monthly spending is about 1500 CHF, so I can save 50% even of that very low wage.
My major monthly expenses are
(1) 650 CHF for rent, water, heating and power (I share a cheap but nice 44 square meter 2-bedroom apartment with my girlfriend, and we share the rent)
(2) 250 CHF for health insurance
(3) 200 CHF for food (buying at a cheap discounter like Aldi and eating only little meat, no eating out)
(4) 30 CHF for internet and phone (60 CHF shared with my GF), and basically no cost for prepaid cell phone
plus a couple of minor expenses and discretionary spending, which tend to bring my total expenses close to 1500 CHF/month.
I am not sure why my costs are much lower than Albert's, there may be some regional variation. In Basel, 1500 CHF are definitely possible, assuming you do not try eating out and instead invite friends over for dinner or make a picknick, and bring your own lunch to work.
I think that due to the high wage levels and low taxes, Mustachian levels of saving can be achieved much more easily in Switzerland than in other European countries. Moreover, Basel is a wonderful city, and Basel's society and politics seem to work much better than what I am used to from Germany. My girlfriend and I definitely want to stay in Basel even after I finish my PhD.
