You're not lost. You're forgetting what insanely wealthy people think about money and how much is needed for them to live as they feel they must, which is different from even ordinary wealthy people. What doesn't pay well for them has nothing to do with the reality of your average rich person......according to the couple's own public statement they intend to "work to become financially independent". I guess doing whatever they do now does not pay well?
Kind of lost, here.
