 Like his rival he is a shrewd businessman and has managed to organize a worldwide financial empire that can easily rival those of Scrooge and Flintheart Glomgold.Unlike them, he is not a tightwad but much more a liberal spender (but by no means a squanderer), he seems to maintain that "you have to spend money to make money", this trait makes his a natural antagonist to Scrooge, who is capable of going to absurd lengths to spare even trivial sums of money.Their rivalry is further contrasted by the fact that Rockerduck was born into luxury, rather than earning his fortune by his own hard work, which is another reason for Scrooge's, and sometimes even Glomgold's disrespect toward him.
