Andrew Ross Sorkin keeps the pressure on private equity players like 740 Park’s Steve Schwarzman and Henry Kravis (who has left the building, but like Elvis, is not forgotten) in his latest Dealbook column in the New York Times. This time, Sorkin seconds the notion that closes 740 Park, namely that “for some inexplicable reason, private equity guys have rarely been big philanthropists — at least not publicly. That’s led to ugly comparisons to robber barons.” Sorkin suggests the public opening of checkbooks. That would be a start.
