Marcelo has no concept of class distinction until he sees three things: that the houses in Robert Steely's neighborhood are closer together than in his own, that Amos's yard is full of faded lawn ornaments, and that Ixtel has to live in a convent that used to be a mansion but now houses more than 40 people. He's so naïve about this stuff that he never mentions poverty in Marcelo in the Real World; we're not sure if he even really comprehends how money works. After all, he's never had to. But nothing says "awakening to class differences" like a private-school kid with his own custom treehouse discovering pink flamingos, Bud Light, and fiddle music for the first time.
