She might be ravin' at the Pittstain . . . but it's Raven. As in, 'a large version of a bird that eats dead things, commonly.'
I'm afraid that supporting herself, in the wake of getting wallduded up in Rindge, plus decades of supporting her deadbeat alcoholic son have put a serious drain on the Pitt family trust.
Considering barely any money at all has been earned by the Pitt family since Oswald capped JFK, it's not hard to draw that conclusion.
Now she's forced the drunken William to leave the money Pitt of Boston, and move up into the boondocks. He's still among Massholes, but it's a lot cheaper up there in flannel land.
DUmmy Jane has to support her worthless son, his tattooed bride, and a new generation of deadbeat Pitts they'll likely spawn, so she's not likely to be a major contributor to WackaDU.
