Reading some ScroogeMcDuck comics coincidentally after reading Daisy Miller got me wondering — Could John D. Rockerduck's popularity in Europe somehow be related to the traditional "old money vs. new money" conflict between old European and American values? Glomgold may be a dishonest Corrupt Corporate Executive, but he is a Self-Made Man like Scrooge. Scrooge's conflict with someone who inherited his fortune like Rockerduck might be more significant to Europeans. Or I could just be far too presumptuous.
I think you're reading far to much into that. In fact, I, even though I'm an European, prefer 'self-made men'. Times changed, I do not believe that the Europeans still (if they ever did as a whole group) find someone who inherited his fortune more important. ('Cept maybe the English.)
Don Rosa writing a Kalevala-themed adventure for the Ducks was highly appropriate. As the comic says, Elias Lönnrot wrote the The Kalevala by compiling various Finnish myths, legends, and poetry together — exactly what Don Rosa did with The Life and Times of Scrooge McDuck. It's a fitting reminder of how all the great epics were written, from 700 B.C. to 1992.
In real life, Scrooge would've run out of business quickly. His workers and families will quickly figured that working for ANYONE else will bring much more money and less headaches. Or worse, he will went to jail soon or later when someone sued him for pay his workers at much more lower than minimum wage. However, since he owned nearly any kind of company (from resorts to oil refinery), he can get away with it since he contributed so much to taxes and people lives that he's practically invicible to law, and people who starved for job will still work with him anyway. The effect is showed in some of Don Rosa and Carl Barks's comics, where Scrooge's showed as the only man in Duckburg that able to pay things like Rocket Project and giant robot's production cost.
