I've got a little bit of a different angle on it. I hate that Jeanette was being so hateful and manipulative, especially in the cab, but it annoys me when Jazz carries on about how they have no say and it's totally up to her, etc. One of the parents said it would cost about the same (a small, liberal arts college costs as much as Harvard?) and there hasn't been a mention of any scholarships, so I'm assuming that the parents are paying.
If the parents are paying, then they do have a say about it, in my opinion. I know Boston is expensive, but I imagine that room and board plus cost of living would be even more expensive in CA. If Jazz is footing the bill herself then, yes, it's totally her decision. If not, it's the Golden Rule. Those who got the gold makes the rules.
I also hated the teaser at the end with her prancing around with her shawl in front of her rapt audience waiting for The Decision of Jazz pronouncement to come down. I realize it's probably producer driven, but it makes Jazz look even more like self-centered, attention grabbing ass.
Of course it's all moot, since she chose Harvard and she probably will never set foot on either campus.
