That sounds about right (right in the sense as that probably how it is and right in the sense that IMHO that's a fair difference). Now would be really interesting to see the same numbers for the US and also have not just the salary but the take home pay after taxes.
Is that take-home pay after a taxes? Is the left column the gross wage, or the cost of employment to the employer? Eitherway in Belgium you'd keep barely half of that. Seems like the Swedes get the better deal.
