I don't recall ever noticing this before. At the end of Ch. 32, the omniscient narrator assumes Charlotte's viewpoint. She really does think that her friend Elizabeth will give in to wealth.
for in her [Charlotte's] opinion it admitted not of a doubt, that all her friend's dislike would vanish, if she could suppose him to be in her power.
And also, Charlotte is thinking of herself! (this was the part I hadn't noticed...)
[...]Mr. Darcy had considerable patronage in the church, and his cousin could have none at all.
So, if Elizabeth were to marry Darcy, more brownie points for the clergy, and perhaps specifically for Mr. Collins and Charlotte!
