I can't speak for Caroline, but for me even aside from the wish money (which is Elijah's, not ours) I work in the bar, I get good money, so I'm alright on that side of things.
And let's face it, if I'd asked for money, someone somewhere would have been bitchy about it. Said we're being selfish, only out for ourselves, blah blah blah blah. Or gone on some moral "but compulsion is wrong!" rant.
