I find this idea that people simply advocate what is convenient/sensible/desirable for them as being the "correct" option, and people who choose to do otherwise should not be protected, a very hard approach too.
The idea of continuing in a high powered career (assuming that you have one in the first place) normally necessitates very abbreviated mat leave and working full time long hours (for all but the very lucky). This suits some, others find it undesirable.
The idea of going part time and taking full mat leaves (my choice) means that career prospects dip but are hopefully not completely scuppered. Again it suits some and not others. Many people do not work in jobs which pay well enough to cover the childcare. Many people feel that the early years with their children are something they will never get back and they want to spend their time at home with them. And so on.
Some people SAHP because they want to, because they can't afford to work, because their OH does a job which does not fit in easily with their OH working.
The thing is that in practice if women are to maintain their standard of living on divorce then they have to take the first option. The second and third options will mean less savings, a big hit to the pension, etc. (assuming that we are talking normal type jobs not extra super ones).
So women either need to knuckle down and work full time, stick with their men no matter what for the financial security, or face an uncertain retirement (at best). Of course the children will suffer in all of this given that they usually end up with the mother, and obviously if she is poor then so will they be.
It seems to me that the way our society is constructed, this idea of no spousal support under any circumstances only serves to allow men to do exactly what they want with no consequences, while women have to toe the line to their men or agree to working full time all through their children's lives. This feels like a real step away from the choice, felxibility & equitable approach that I thought we were moving towards.
For instance pension rules have recently been changed so that women can receive full state pension with less years work. Presumably this would need to be reversed for the sake of fairness to men.
This is all going backwards, isn't it?
