I can see that this would appeal to some, but why her daughters would have a struggle with getting on the property ladder, I cannot imagine. They'll probably have a property portfolio to fall back on with a parent like her.
I like Kirsty Allsopp, but she does come out with a few howlers every now and again. I don't see her as a feminist in my understanding of the word, although she seems to be an independent woman who will tackle many things and not depend on a man to help her, and in business I could see her at the top of the ladder.
I wouldn't push mine in the direction she suggests - I encouraged them to spread their wings and see the world, not think about houses, babies or university but find out what they wanted to do with their lives. One had a gap year and visited Australia and the other moved out to live with her friend for a few months, then returned home. Within a few short years, they'd done their degrees, met partners, bought houses and had children in their late twenties.
