Dsiagree. There's too much anger in her for it to be just that.
I agree. I know money is a motivation for some people, but I think Maines is from a connected and privileged background and is not motivated by money. She wants what she conceives of as intellectual or artistic "respect" or cachet.
There are different types of "money" or currency. Some people want egotistical or artistic or intellectual respect, cachet or "currency" or validity to their way of thinking.
Maines is looking for what she imagines to be "intellectual" respect. She's trying to overcome a poor body and self image. She doesn't want to be "country" anymore.
She's like all the Hollywood "stars" and celebrities trying to look "smart" by wearing little eyeglasses. It's not enough for these people to be "stars" anymore, they want to think they're really smart, intellectual and important.
Good luck.
