Two things : first, just look around if you want to see a sexist world. Delve into history if you want to find a sexist setting (victorian england, or just medieval europe.) Also, if you examine certain modern cultures you'll find plenty were women are just "cattle" in the eyes of men.
Personally I just go to either second hand bookstores or budget book stores and browse the history setting, you'll find heaps of cheap books for background setting, or try the sociology setting. shouldn't cost more then a few dollars. (that is, if you have acces to such a store).
Second : I used to gamesmaster a homebrew where the elves were the uber-race, enslaving the humans and orcs. Halflings were honoured servants. For them, a half-elf was an abomination, and should be killed on sight (I kinda stole it from a fantasy book of wich the name escapes me). The game played on a tropical island, wich the elves had recently kolonised. 'twas good fun.
