It's surprising to see Switzerland coming up here, as its being among the most expensive places in europe. Pretty much every other european country will be more affordable.
Switzerland is indeed extremely expensive for most things, but consumer technology is actually OK here. A low sales tax of ~8% actually makes some products made in China cheaper here that in Germany.
Oh, and a lot things like infrastructure actually work out cheaper because of the massive investment sunk in up front. It is a case of spending more now, to save more in the long run.
In Switzerland, it is forbidden to be poor and it is forbidden to be foreign. That's from one of John le Carré‘s books. Not verbatim. I think it was The Perfect Spy.
also mobile plans are cheap in Switzerland. You can get a plan including unlimited calls throughout most of Europe+Canada+US (incl. roaming) plus unlimited 5G in Switzerland plus 40GB of data roaming throughout Europe (not only EU)+Canada+US for 35-45 CHF/month. These are sales that happen 3-4 times a year, e.g. via qoqa.ch or on wingo.ch. I have two of those from two different providers.
Regular prices for such plans are CHF 100-130, which I also do not find overly expensive compared to US.
