And here I am in Belgium, paying 2000 a year for a Masters degree.
Also, half your paycheck goes to the government and European tech salaries are nearly half that of the US. There's no such thing as a free lunch.
The big difference in total compensation after tax between Western Europe and USA is in the compensation part for people that are considered highly skilled. For example for me I get at least 2x here in CA compared to what I would get in Norway and Switzerland. In the UK and Germany the difference is even larger.
For people that are not highly skilled it is the other way round, they would earn significantly more in Europe. Another difference there is that life in Europe is much nicer for the average middle class, but personally I think it’s nicer in the US for upper middle class, the top 10%.
