"I don’t even consider myself wealthy, which is an interesting thing," she told Fox News host Neil Cavuto. "It can be here today and gone tomorrow. And how I measure riches is by the friends I have and the loved ones I have and the people that I care about in my life. And that’s where my values are and that where my riches are."
So she does not consider herself wealthy and considers wealth to be the number of people that you care about. Sound to me like she is indeed a poor person.
