Go to Paris, I have 5 years of experience but not exactly outstanding and yet I get 1 or 2 offers every year without pushing too much. 10% income tax is on you

Go to Paris, I have 5 years of experience but not exactly outstanding and yet I get 1 or 2 offers every year without pushing too much. 10% income tax is on your take-home salary. From a different perspective my take-home salary after tax is less than half of what I cost my employer, i.e. if I'm paid €2,500 per month I actually cost my employer slightly more than €5,100 (and even that is ridiculous compared to what people pay in countries with similar income level)
