Teddy Roosevelt was the son of a wealthy and famous railroad baron, but he used that upbringing and status to rein in corporate monopolies and bust the oil barons' empires wide open, which started the decline of the gilded age. All that to say, being a wealthy, elite and privileged oil heiress doesn't necessarily mean this person doesn't want to end oil consumption.

(I don't know anything about her.)

If it is, would that bad? Seems like a person who might really have strong personal investment in the situation. Using the oil companies' profits to try to shrink them, seems good.
