Raising children and homemaking are important roles that should be appreciated and respected. But, I think mostly men are to blame for not appreciating women in those roles. Back in the day, most women did not agree with feminists who criticized other women for staying home with their children. But, many men sure liked what those early feminists were saying (and doing).
Keeping the home fires burning and caring for and bringing up the next generation are actually more important than a job.
If you have a great career, and you die, you may be missed, but replaced fairly quickly. Nobody replaces a lost mom.
