I've taught in schools where some children come in hungry with families that are clearly struggling
That's not the fault of this woman who decided to spend 10k of her own money, on a playhouse for her child though.
The world has always been fucked up in strange ways and that will never change.
We have children/parents who are arriving at school/work with not enough to eat, and we have also have a massive obesity problem at the same time.
Just because one family eats far more than they need, and another family has to eat less than they need, does not make the former family 'crass'. They're just spending their money on what they want.
Same with the woman in the story.
