Chelsea going to have to find a job. No doubt she’ll run for office.
She and Marc would still have a tidy nest egg after selling their New York digs and purchasing a home in non-millionnaire America. From a financial standpoint, neither of them needs to work except for purposes of elite status competition. If I were scripting the next chapter, I'd suggest that they move the inner city, or an Indian reservation, or if that's too hard for them, a small town somewhere in flyover country ... and teach middle or high school. It would be a better place to raise their kids, and with luck, they might even encounter enough reality complete their educations.
