depression

[Candico86@aol.com]

I was reading the Don Rosa timeline a few days ago and he mentioned the 
depression or the collapse of the stock exchange in Duckburg.  In real life, 
during that time thousands of people lost their whole fortunes and that time 
was at the peak of Scrooge's fortune.  Just one year later he became the 
worlds richest duck.  If Don or anybody else knows how Scrooge could have 
maintained his vast and humongus fortune during the depression, I would like 
to know how.  Thank you.
