Women in top jobs of course need help today to make it work. But their employees are not servants- a qualfied nanny is as highly paid as a primary school teacher- and very well looked after and respected. Very different to slaves. Cleaners and gardners are paid a good wage, and all social benefits, etc- by honest employers. So a woman who works provides proper employment for others too.
I do hope you come back Leticia- and I do apologise if I misread your posts- although I am not sure how. You are clearly saying that couples who are both talented, both hard-working, both love their job and are keen to progress in their career- should either not have children, or toss for who gives up their career- as it is impossible to be good parents otherwise- and that one has to give up their professional 'ambitions' (for fear of a better word).
BTW, if a woman works part-time after having children- an accident, school play or sports day can still happen during her working hours. In fact, employers are far less likely to be sympathetic if someone works part-time and asks for time-off. If parents work very hard- it is much easier to put their foot down and say 'I shall take the morning off for the school-play' etc- and of course, women who are Senior Managers and do their job really well, can organise to deputise and give instructions that will free them for said school play. The higher the job, in many ways, the more in control and flexible you can be. It can work- it does work - but yes, it is very hard ... work. I take my hat off to those women.
