In my opinion it is very hard to compare the wage differences between company like anybody is trying here:
check:
- differences basic pay/gross pay incl. per diem,hr-pay etc.minus tax
- pension regulations
- housing allowance,school fee
also there is a huge difficulty to judge future development,e.g. tax system ,housing allowance might change..
also cost of living calculations are of course incl. housing, so if this is taken care of you have a totally different situation.
to cut a long story short,at the end I believe it is dependant on how much RISK you are willing to take if thinking about moving out of good old europe.
