Xenia-there are lots of different people in the world-we all have different ideas, different philosophies, different abilities. There is room for all. If everyone followed your view on career there wouldn't be enough jobs (there aren't anyway).
It seems beyond your capacity to understand that you can be ambitious, very busy and fulfilled without having to earn masses in a full time job. If I did have a high flying career and no children I would want to get off the ladder as soon as I had earned money and do something like keep sheep in Wales and spin my own wool etc. (probably not that specifically-I haven't given it a lot of thought not having pots of money.
I would certainly expect to retire early and have time to enjoy myself with what I had earned-have a change-volunteer for things.
JK Rowling would never have made her fortune with your way. Sitting writing in cafes with a DC because she couldn't afford the heating. You would have had the DC in a nursery and her climbing some career ladder.
There is no room in your system for the creative, the artists, the lover of the outdoors, archaeologists, museum curators etc-those who earn a pittance but have a ball doing it.
As a role model to my DCs I want to say-have choice. If climbing a career ladder and pots of money is not for you don't do it. If it is what you want then go for it! But don't think you have to do anything.
