I have a snippet that features an upper-middle-class woman with lots of unexamined privilege and a nearly-homeless woman who has been living on her wits for quite a while. Class differences aren't as obvious in modern day America, but they do exist... my poorer woman has to balance the security of living with someone who doesn't mind giving her a bit of financial support, have to worry about money, with the sometimes insulting assumptions her partner makes. And they do love each other.
