Indeed there are a tons of things to consider
Things here work somehow different as in the US, some things are cheaper somethings are not. I must say that we relocated from CH to the US (Florida), lived there for about 5 months but came back, our experience there wasnt very good, but I will try to be fair on what I have to say:
What is true there are tons of things that are not comparable.
For example:
Fuel prices are really high, interest rates are little higher and it is not that *easy* to buy a car as in the US (walk in the car shop and leave in 30 min with your car). You gotta pay taxes, (based on the engine power), insurance is not that cheap either, etc, etc,etc. So whats the deal then? Deal is that most people use cars only for leisure. Of what I have seen here in CH, what people usally do is move close to where they work (opposite as in the US, changing jobs is something that people normally dont do unless there is a strong reason for it, in other words when you take a job; expected is that you stay with that job for years (hence the 3 month probation you normally get before you decide to stay in your new job). Having said that, you will find that Switzerland has a very good train and bus system, also in the major cities you have trams. People walk A LOT around here, bicycle is the prefered transportation system. People are very respectful for cyclists and streats are very well marked. Both my wife and I have been living here for about 5 years, we didnt have car for the first year, we got one afterwards because shopping may become complicated with a bicycle, however we only have one car. Bottom line is that here a car is more commodity while in the US you cant live without one.
Food, this is an interesting thing. Expensive? We found the prices roughly the same as here (usually we shopped at Publix), however the quality is not comparable at all, most of the products are canned and even if the aint they taste like plastic or have a certain artificial flavour. Try comparing the prices of BIO products with regular products here, that is the closest you could get quality wise , and you are still not even close. Parmessan cheese for example, if you buy Kraft for sure its cheap it doesnt taste at parmesan at all, get the real Parmesan (US$ 3.5 100gr if I remember correctly) thats almost twice what you pay here. If you gonna move here, forget about meat !!!, that is a HUGE luxus, cow meat that is, Pork is relatively cheap. That is something we really miss (besides those kick ass BBQ Ribs from Tony Romas )
Good thing is that there is no Credit History here, so you dont have to worry about building one. That is because you pay everything cash (very few stores have credit systems) ... yeah that somehow sucks.
Be aware of something regarding taxes, you get taxed at income, tax depends if your married, number of children, religion, etc. If you are married with 3 children then you are in a very good tax level, plus you get 150 Chf monthly for every child from the state (called Kinderzulage). Also people with at B-Permite (something like HB-1) pay fixed income tax (called Quellensteuer - taxing at source), still not sure of that is a good thing or not, but most people say its better, I actually dont care about it that much as its not "optional".
I would say 140K is an awfull good salary!!!!, I have a collegue that his monthly income is around 8200 (before taxes), he has two kids and they are able to live very confortable. Salary of course depends where the company is located, salaries in Zürich are relatively high, but also living costs are higher, but taxes are lower (funny huh?). I live in Kanton Thurgau, apartements are really cheap (would say 30% cheaper) but I pay around 6000 Chf more per year on taxes ... yeah I know thats weird . Therefore I am moving to Zürich in two weeks
Clothing and electronics is something that you would really miss, that for sure is really really expensive.
There are a handful of advantages of living here:
- Italy 3 hours drive
- France 2 hours drive
- German 40 min drive (5 min WALK from where I currently live)
- Austria 2 hours drive
You can get cheap flight tickets to anywhere in europe, go to Londo for the day for only 20£. Plus you get a great opportunity to learn other cultures and other languages, and drink some nice beer
One very important thing: Once you get a work permit, your wife doesnt!!! She will be allowed to stay, but not to work unless she finds a company that is willing to sponsor her work visa, and that is not an easy thing!
If I would be in your shoes I would plan to come and stay for a couple of years, that is having the possibility to return to the US. Perhaps you stay ( as I and many others did) or perhaps you dont. One things is for sure, its worth having the experience.
