You're not European I take it? Even in places like Italy and such, you can get like €30Κ per year and be happy about it. In most of E.U. it's even less.
Hah, OK. Thought it maybe was a typical "you make so little?" sneering response Europeans often get from US developers in forums such as HN.
Which for some places in Europe it might be a good comparison, but for others making €40K a year might get you a far quality of life than what you get in the Bay area or the US in general for $100K (e.g. larger house, better savings, insurance, 4 weeks paid vacation, decent working hours, etc).
