Seriously 2.5k? Like the equivalent of 2500 US dollars (since Euros are at near 1:1 parity right now)? I looked it up and apparently the average salary in the Netherlands is 36.5k Euros. How is a principal SE making 20% of the average salary in the Netherlands?
I know some countries use decimals like commas are used in the US, so maybe that's actually 25000 and 60000, which would make more sense.
