Well, having had a few times the opportunity to do such a move, I stayed at my previous job. Good atmosphere, cool company (a big one), located in such a way that my 15 km bike commute is 70% in a forest, no travel, yell at my children every night so that they do their homework/wash teeth etc.

What would these 100k give me? Not much - I will comfortably retire when time comes. I would consider a 500k increase as it would change my life and probably help me to retire earlier.

I belive that what revenue brings in a set of plateaux. When you start every euro counts, then comes a plateau and you move up after a significant change of salary. Which brings some acceptable/bereable drawbacks.
