Nah. I'm not that familiar with the ducks, but I always pegged Scrooge to be a Cool Old Guy type - not to mention that he's completely self-made.
Scrooge McDuck reformed himself if anything. Not that you can make any logical CANON timeline between Disney's Christmas Carol and Ducktales, but...
In the former, he did the Scrooge thing and saw the light in the end.
In the latter, he was sometimes cranky, royally obsessed with money, but I don't ever remember him acting like a snob about it. Definitely not the stereotypical CEO of our world. And where someone else would give himself a pay raise, Scrooge went on a treasure hunt.
