Theory: For men in heteronormative relationships (which I don't hold up as an ideal but do believe are prevalent enough to heavily influence the stats): Married men are more loyal to a company while the company is paying them. If you fire a single man, you just punish them. If you fire a married man, you punish their family. Therefore they are more trusted in senior positions where they might have to make calls on the organisation's behalf which might conflict with the individual's ethics (as they are made secondary to the primary motivation of breadwinning), and these positions tend to come with higher salaries.
