Your salary number is off the mark though. Median pre-tax income is roughly double that.
There's no problem getting rich by working in Sweden if you keep your costs in check (which is hard to do these days), don't over educate yourself (also hard with high youth unemployment) and eschew some of the social benefits by working in less comfortable conditions (which is becoming the default anyways).
Doesn't mean you'll be super rich just by working of course, but that's not really true anywhere. At least not if your family isn't already. If it's really a priority one could of course leverage the competitiveness of most Swedes education, attitude and knowledge of languages by going to Zurich, London or (a large city in) the US for a few years.

So almost the double of what you said.
The unemployment rate for educated computer scientists is around 0.4%.
Entry level median salary for devs without higher education from the year I left recruitment (2013/2014) was 28000 USD per year. Add 3000 USD for entry level devs with university/college education.
YMMV but I don't think things have changed that much since then.
I had a look at some old notes and stats from 2012-2013. Knowledge in JS, Php, Java, Python or C/C++ were required for all of the positions.
14 recruits in the 18-20 yr, no edu bracket (high school dropouts/just graduated), mean salary 24451 USD (199200 SEK)
24 recruits in the 18-20 yr, bootcamp/vocational edu bracket (high school dropouts/just graduated), mean salary 27249 USD (222000 SEK)
17 recruits in the 20-22 yr, bootcamp/vocational edu bracket, mean salary 28869 USD (235200 SEK)
29 recruits in the 20-26 yr, higher edu bracket, mean salary 34467 USD (280800 SEK)
These were placed with employers, startups and established companies, in the tech sector. Mainly in central Stockholm and Kista (tech hub outside of Stockholm).
Make what you will of this, the amount of job seekers with bootcamp/vocational education hasn't gotten less than in 2012/2013. I believe this keeps the salaries in Stockholm down, and makes you settle for less if you want the job at all. Entry level salaries for devs in Stockholm are low.
BUT - as soon as you get some experience under your belt, you can rise quickly in salary by job hopping for a year or two.
But sadly most of them are unemployable for tech-firms. Sweden, like most other places, has a shortage of well educated engineers (and other young professionals).
Much of higher education is Sweden is very low-quality. For example, there are government subsidized university courses in Harry Potter knowledge (no joke).
A good sysadmin can make around 60k USD /year in Sweden.
Good developers make several thousand more.
