The latest rumor out of 740 in the wake of the devastating fire there last week has it that Bernie-Madoff-feeder Ezra Merkin‘s duplex apartment, where the blaze began in a sauna, was thoroughly destroyed and that controversial conservative billionaire David Koch might buy the charred shell and add it to his own apartment just below, creating a quadriplex that will rival the best and biggest residence in the building, private equity kingpin Steve Schwarzman‘s duplex-plus-servant’s-mezzanine, once the home of John D. Rockefeller Jr. Does this qualify as #richpeopleproblems?
