Perhaps some intrepid investigative reporters should take advantage of her “me time” to travel to Boston U and find out how she managed to garner a degree in economics. Talk to her professors, people that knew her. We don’t have much of a back story on her. We haven’t heard a word from old boyfriends / girlfriends. Call me curious
Perhaps that school, or at the very least that department and degree program, is a complete farce. She obviously knows less than nothing about economics. She actually has negative knowledge on the subject - she is sure she knows things which are in fact just plain wrong.
The other alternative is that she "earned" her degree by augmenting her assignments and evaluations using ah, shall we say, "other skills."
I'd put either possibility at about equal probability, with either being about 2 orders of magnitude more likely than she actually knows anything and just mis-spoke.
