The slice-of-(very highly subsidized)-life series “Rich Girls” (9:30 p.m., MTV) wraps up its first (can there possibly be another?) season. Once you look past the servants, the mansions, the private jets, the expensive restaurants, the trust funds and the endless label name-dropping, “Girls” was really not about money at all. At its core, it followed two very self-conscious women making that painful transition from child to adult.

Most of us can thank goodness there weren’t cameras around catching every moment of this ugly larval stage. Jaime Gleicher may be writing her first novel and going on to an Ivy League school, but she’s developing a permanent scowl that could require professional attention. And will Ally Hilfiger ever learn that you can’t mask selfishness with the pretense of sympathy? Isn’t it odd that this MTV series dedicated to two girls’ wild, youthful abandon showed them turning into middle-aged Manhattan matrons before our very eyes?

In stark contrast, “The Simple Life” (Fox) remains emotionally opaque. As the two Beverly Hills harridans run rampage through the Ozarks with no regard for anybody’s feelings, one can’t help but wonder, “Were these two girls raised by wolves?” Tonight, Fox offers four consecutive chances, beginning at 7 p.m., to catch up with the series.
