> A regular employee/salaried dev is looking at at least 90k euro/year in nl

According Payscale, the average salary for a developer in Netherlands is 41k Euro/Year (http://www.payscale.com/research/NL/Job=Software_Engineer/Sa...), and in Amsterdam, the capital, 53k (http://www.payscale.com/research/NL/Job=Senior_Software_Engi...).

In Copenhagen and Barcelona (the two Euro cities where I have worked) 90k is totally off the market.
