>>77013983Smaug is definitely third if $crooge is #1. Flintheart Glomgold's only the second richest duck by a hair's width compared to $crooge. Their net worth's are theoretically identical, but being the frugal old bastards they are, they count the string in their pockets for a tie breaker if need be. Also, their ever-growing collection of treasures.
>>77014412Nobody can get THAT rich unless you're in it for the sake of achievement. McDuck considers the title of "The World's Richest Duck" as his validation for being 'tougher than the toughies, and smarter than the smarties' - but the fact that he's got so many dishonest rivals trying to one-up him, he never squanders his wealth on needless extravagances to give his competitors an edge. He's earned everything he's got square, and he'd never let any Beagle Boy or crooked businessman dethrone him of his title through cheating or thievery, when he had to work his whole life to get to where he is.
He also puts a lot of sentimental value into his earnings, to the point where he can basically tell his dollars apart by where he earned them.
