It’s ripped off from The Time Machine. No, not the recent abomination or the '50s George Pal movie, but the original novel by H.G. Wells, published in 1895. The Eloi lead idyllic, if vapid lives, supported by the brutish Morlocks, who toil underground. Don’t feel too sorry for the Morlocks, though, as they use the pampered Eloi for food. For Eloi read “rich” and for the Morlocks read “workers” and you’ll see what Wells was getting at.
