Shreiking Harpy...ah but women ARE competitive...have you not heard the "my child was writing sonnets at age 6 months" shit that goes on at some of the school gates???? That test was just about what men thought of as important competition (i.e cash and looking good in front of evryone).
Men do seem more motivated by personal reward...but is this good? And does it mean they are better or nicer? And how is it relevant to child rearing?
My (male) friend calls male comptetiveness "willy waving" and says it is in built, and a bloody nuisance.
And yes, in a society where one sex has arranged social and work structures to favour someone who will turn up all the time and sod everyone else, then this will favour male working habits.
I was once "tipped for the top" of my work, then I realised what a shit corporate culture it was, all Blackberrys and staying late and all that rubbish and I just couldn't be arsed. I think the number of mums who start their own business after children shows that women like to run things, but not in the current male dominated corporate cultures we have today. Of which banks are the worst, followed by any sales department...and my brother is one of those who avoided going home till the kids were in bed as he "just couldn't stand that stuff" and someone's got to put the kids to bed, and most men know that, if they sit around doing bugger all, the woman will do it...
Note small boys who let their mums tie their shoelaces even though they are capable of doing it themselves.
