Move to Sweden as a Support Engineer

no one?

Your post is hard to follow, in part because your inquiry is intertwined with unnecessary comments such as "I always wondered", "both make most of their daily struggle[,] I guess", "I just hope they solve it at some point", and so forth. Other phrases such as your wish to "pay every insurance I may ever need" are unclear.

Taxes are unreasonably high in much of the EU, and tax burden in Sweden is one of the heaviest worldwide. The idea of welfare economies' "good quality of life" is an overstatement. In reality you would be supporting the finances of more and more of those economies' aging population.

The high turnover in the US is a result of the at-will employment doctrine that applies by default in employment relations there. The parties could override that doctrine in their contract, but candidates are afraid that even proposing some alternative could deter the employer from hiring them. Candidates don't even require from employers any reciprocity regarding an n-week notice of resignation. By contrast, labor markets & politics in Europe are less flexible, more protectionist than the law of supply & demand. Europe's protectionism and systemic rigidity are a double-edged sword: The turnover is lower than in the US, but so are salaries, career progress, and ultimately your purchase power.

Another factor that keeps salaries low in the EU is employees' leniency as to remaining underpaid, a pattern that only professionals from elsewhere (US, Switzerland, Singapore, etc.) are likely to notice.

@pragmatist thank you, yes my post is not super easy to understand, the context is quite complex, but I see that you mentioned important things anyway, so your understanding wasn't so bad.

My salary can be compared to one in US, but it doesn't make me rich in UK, thinking that in Sweden I'd get more wealth/security with more taxes and half salary, it sounded immediately bad, so this is the main thing I wanted to underline.

With much less cash left, I thought I can forget an additional health insurance (not super necessary in Sweden but as a foreigners complications are higher), unemployment insurance, I didn't see any permanent income insurance in Sweden but probably I don't know much about Sweden.

I still have to explore critical illness and essentially all the necessary ones, so I'm not fully aware of how it works in Sweden for those.

At the same time, I see a lot of openings in my field, it should be easy to find a job, but I don't see the wealth coming, or maybe I reached too much in UK which is hard to reach anywhere else.

A foreigner that doesn't speak the language spends even more money than a local (translations, travel back home etc), usually you're paid more if you go in a country where you don't speak the language, and I talk by experience.

I don't see that in Sweden, and despite it's genuinely respectful, business doesn't know respect, so this 1:1 comparison is very discouraging for me.

This + the half salary doesn't make Sweden a good choice, what do you think?

Beware of what is known as ghost jobs. Back in 2012 I made the mistake of quitting my job in the US upon scheduling job interviews with several intermediaries in Europe who expressed interest in my profile. All those hiring processes turned out to be fake.

Ghost jobs are common also in the US and the rest of America, but they are much more prevalent in Europe.

I agree. Unfortunately the same conclusion applies to much of Europe.
