Another reason people don't often take into account is that men have an extra incentive for earning more money as their worth as a person is judged more upon what they make than it is for a woman (women have other things they are judged more upon). So each dollar, beyond the utility of having an extra dollar, also makes them 'more of a man' to use a phrase that tries to condense all of complexities of society's judgements down into 10 letters. Many of the explanations commonly given, like men being willing to take on more dangerous jobs, can be partly explained by their judgment as a person (and as a parent) being derived from what they make to a stronger extent than for a woman. >women have no interest in money Just to clarify, there is a difference between no interest and less interest, and also a difference between interest in money and interest in the status associated with a certain level of salary/income beyond what comes just from the money earned.
