Working in Europe I can never believe these fantasy numbers from the U.S. 250k USD after 5 years, seriously? A good Senior Developer here, with 5-10 years of relevant experience, might have a base salary of around 50-60K EUR, and perhaps another 0-2K EUR in bonuses. Then you have to pay around 30% income tax and another 20% if you hit a certain income bracket (which you do with 50K) in many Western European countries. If you want to make more you need to do contract work or roll your own business.
