In a violent scene from the latest film version of the F. Scott Fitzgerald book "The Great Gatsby," old-money Tom Buchanan vilifies Jay Gatsby for taking on an upper-class persona. That was a different time, of course.
Now, with so much economic, social, and cultural upheaval, Gatsby would be interviewed on CNBC for how he created wealth, through crafting his mystique. Some of it would be viewed, though not overly harshly, as unethical, but shrugged off. Our era is increasingly amoral. What's key is not getting nail for anything illegal.
Another difference, of course, is that new money is no longer treated as crass. New money creates jobs, provides funding for political campaigns, and attempts to wipe out diseases like malaria.
