This thread has fallen into the ridiculous. When a person has millions of dollars of disposable cash, and they decide that they will only drop $1,000 a week on shopping, eating out, hanging out with friends, they (the person with millions of dollars of disposable cash) will likely refer to themselves as “living on” $50,000 a year.
It isn’t the same as having a job that earns $50,000 a year, but I think people with a reasonable sense of reality will be able to grasp the difference without getting all stupid about it.
She gives herself $1,000 a week in walking around money. It’s smart of her. It keeps her attentive to what she is spending. It will keep her with that kind of walking around money for decades to come even if she never gets another job.
You seem to want to ignore the article and quotes, and create your own version of things, for instance defining for us exactly what she means.
What sources are you using that we aren’t seeing?
