It says in the article that her housing expenses (outside of property taxes) are 8k-10k/month.
In reading it – the mom works hard at her career, but is struggling to live in that house and live at her former standard of living. (Where she could spend without thinking.) Lots of stress ot keep up appearances.
On the other hand – her Nanny lives in the same house, has the food/lodging/utilities paid, and makes 50k or so… She’s doing pretty well, even without medical benefits.
The kids would actually do better with the life lesson that chores are good, stuff and things don’t buy happiness, etc.
