I do wonder what the actual statistics are, on the gender pay gap, @everychildmatters - I do believe that it is changing, and more women are earning the same as/out earning their partners, but I also believe that this is not the majority of women.
I suspect that it is still far more common for the woman to give up working or to go part time, in order to look after children, which does have a knock-on effect on their future career potential and earnings, and contributes to the continuing gender pay inequality. And we are also still fighting against the tide of history - because women generally have been the ones who were the SAHPs, employers still feel it's OK to pay them less or to pick a man over them for promotion, because he's not going to get pregnant and need Mat Leave. Sadly, I also think it's true that a lot of the jobs that women end up doing - caring, nursing, cleaning etc - tend to be less well paid, so when a couple is looking to see who will stop working/cut their hours to look after the children, the lower earner, who is the logical choice, is the woman.
I think what I'm saying is that, as a rule, women tend to earn less than their partner/husband, so it isn't gender stereotyping to state this - but it a sad and unacceptable fact, and absolutely IS something society should be moving away from, much faster than it is now.
Men need to be equally willing to stop work or cut their hours, to look after their children, and employers need to pay people the same wage for the same or similar jobs - that might start to move things in the right direction.
