I think this is a fantastic pointI dont think its about SAHP at all. It is really the individual and their drive, etc.
You can be a working parent in a dead end job and hate it, have no compulsion to work harder or be better or work yourself through the ranks so I cant see how that sort of working parent would help....using your example.
But you could have a SAHM that is driven, that bakes and cooks and sells these things at the local markets, that loves to read and learn new things and takes short courses to better herself and therefore can then share that with her kids. So is that mum worse then the working parent that doesnt have any career focus?
Some of the SAHM examples are about the parent themselves. Yes they stayed at home and looked after their kids but maybe they themselves didnt want a job or career....that they just wanted to be at home? Some people are just like that.
I know lots of people that hate work and have no career aspirations and I certainly wouldnt send my kids to them for a working role model!
I am a SAHM but I now run my own business from home, look after my kids, help with homework, look after the house and cook and bake and do after school playdates too. I think I am an awesome role model for my boys and daugther.
