Katie and Greg's middle-child, 12-year-old Oliver is clean cut, self-assured, smart beyond his years, articulate, and a self-professed fiscal conservative. Oliver is the kind of kid who refuses to join in his school's food drive because it promotes a welfare state. Instead, he's a disciplined little capitalist who's saving for his next share of Apple stock. Deep down, though, he's a good kid, and uses his wits to find ways to help people and develop his portfolio.
