What jobs would she get?
She probably doesn't need a job, given her family's wealth, but her father is well-connected government official. I'm sure he could get her a position at some agency or other, if she really wanted one.

No, I don't know her net worth for certain, but it isn't a stretch to say that she comes from wealth. It's a lot easier to get wealthy people to give you a ton of money if you're also wealthy.
