I actually see nothing wrong about people rich enough to be able to devote their time and energy to their children. If I had the choice I would definitely do that rather than endure certain work situations. Work is often too glamourised. Most of 'work' is repetitive, boring, and you get little thanks. If you are lucky enough to have an opportunity not to have you and instead raise your children, take it. ''Having a career' is more about getting mothers off benefits.
Im a feminist and to me that means people having a choice.
Raising children is hard arduous work but a very important job, not a sideline to be fitted in in the evening or weekends.
