I tend to have a love/hate relationship about books with rich kids. Done right, I like and feel sympathetic towards the rich main character, or treat the book as escapist; but done wrong, I turn into the "get a real problem!" type of reader with a side dose of "and imagine if that were your problem and you didn't have any money!" Yes, Holden Caulfield, I'm looking at you.
Carlie takes issue with a column that says all YA is about the rich folk nowadays (she also takes issue with the conflating of YA and middle grade, but that's another issue.)
I know we've done this before, but heck, let's do it again! (See here for our look at Class in YA books).
List of YA/middle grade books, written in the past few years, that do not have Rich Kids as the main character. Yes, I'll count struggling to stay in middle class as not being rich. Let's try to keep this contemporary, that is, not fantasy or historical fiction.
