That is still an apples and oranges comparison. Mark Zuckerberg is invested in tech which is an industry that was just barely creating itself in 1976 and he started with nothing and turned it into $100b. He jumped into a market that was still trying to define a market leader and took the spot creating naturally occurring growth from winning the majority share of a brand new market. It was an astounding feat and you can make the argument that it is way more impressive than what Trump but what he did was different. It is fairer to compare what Zuckerberg did within tech and new business development to others like him and Trump to someone like the Hilton family or any of the other mega real estate moguls.

Trump was given a head start and he still can't break into that stratosphere. That's why I define him as merely "good." True growth blows away what the V500 could do and that takes true gifts.

Trump was given real estate holdings and cash of about $1m(by his definition) to $250m(absolute max estimate of his father's estate in 1999 ignoring that he had siblings) into an empire of $4.5billion by investing in real estate with stiffer competition and already priced in successes. Comparing him to Zuckerberg operating in an unregulated market to Trump operating in a highly competitive,thin margin, and regulated market place is a mistake.
