I really hope that this is a wake-up call to her. While it is easy to be negative towards her, hopefully she can be an example to others in a various situation. There are way too many people that are making absolute bank, but still live paycheck to paycheck.
I don't know how the public school system is in England, but is it necessary? I feel like people that send their kids to private schools here in the US are doing it more because that's what their friends are doing. What makes it harder for people like the lady profiled, is that it means they will feel encouraged to buy nicer clothes because that's what their kids classmates and parents are wearing. The lady mentioned feeling envy towards another mother's clothes and elegant style.
For me, while I don't live as extravagantly as my peers, at least I am not concerned about having money to fill up my gas tank, nor do I carry debt on my credit card.
