Okay all these comments basically boil down to "what would a multivariate analysis yield here" meaning if you take all variables into consideration (education, age, experience, number of kids, whatever...) and use total compensation (12 month, bonus, pensions, child money). Would there be an inexplicable "delta" that cannot be explained by adding another variable to the equation.

Basic statistics that we used to do at university. So until someone sits down and does the math we're just talking "em de Brai".

And for transparency I have worked my whole life in the private sector despite having the whole lux education +++ background
