exoticfruits I'm not sure I've got your points straight. You say you think there are no enough women at the top, that you don't want to be at the top and you don't think many others do and that it is up to individual women to clear their lives so that if they want to achieve that, they can do so. That is, in fact, the problem.
Most top jobs do not actually require a person to completely give up their lives in order to do the job properly. To the extent people are expected to do so now, it is relatively recent, coinciding largely with the appearance of significant numbers of women who are capable of doing those jobs. 
If you think that there should be more women in senior jobs, it's not sufficient to say that women must make arrangements so they can devote all of their lives to the job. In fact, many men in senior jobs spend significant amounts of time on activities not related to the job (writing books, being boards of charities, pro bono work, climbing fucking Kilimanjaro) which are all seen as legitimate whereas spending time with family is not. As I said up thread, in my fairly limited experience of working in Sweden, men and women in senior roles would get up and leave important meetings to go to their children's school activities and would talk openly about their childcare arrangements. I believe this attitude would contribute to more senior women in business. Another poster made a comment about paternity leave - I believe there should be a non-transferable right for men to take longer paternity leave. Quotas for senior representation are also something I would look at closely.
