I am Swiss, through marriage, and live in the French speaking part near Geneva.
It is a stunning country physically.
The wooden houses, chalets, are typically less expensive than your normal build in an urban setting, however the most expensive part of any house purchase here is the cost of the land. Unless you want to own a chalet in a ski resort, then a wooden chalet can be astronomically expensive.
In our house, we don't have a bomb shelter, instead we pay a tax to our local commune, which I guess gives us access to the communal one of needed.
We don't have Amazon, but we have Galaxus which is similar. We can use Amazon.fr or Amazon.de, pre brexit could use Amazon.co.uk, and have our goods shipped to a holding address in nearby France, and hope we don't get caught by the customs on our return to Switzerland after picking up our packages.
What I know of Swiss schools, my kids go to International school, is the education is very rigid and any kind of leaning differences are difficult to get supported. However they usually have fantastic integration programmes for non native speaking kids when they join a local school initially. Kids are streamed very early in their education either into an apprenticeship stream or university stream.
There is no public healthcare, everyone is obliged by law to have medical insurance, which can be expensive even for the basic insurance.
At one point, Switzerland had the highest rates for Covid in all of Europe. There was a point when hospitals did appear to be feeling the pressure, particularly intensive care beds, and there were media discussions about the possibility of opening up military hospitals, but it didn't happen.
When masks were compulsory, I think everyone complied with the rules, I never saw anyone NOT wearing a mask anywhere during that period.
Life is expensive here, particularly as labour is expensive, so costs of things like tradesmen, domestic help are very high. Salaries are high and taxes are low, but that is changing.
Aldi and Lidl have now opened in Switzerland and that gives more choice, before then it was Migros and CooP, which seemed to be working on a cartel basis.
I like Switzerland, but I do find it somewhat boring. Try to get a late lunch anywhere and staff will look at you like you have asked them to hand you the crown jewels, same as trying to get a late dinner.
Overall, though, I am not sure where else in Europe I would like to live if I didn't live here.
