740After an annus horribilus full of troubles, is 740 Park, subject of my 2005 book, once again New York’s Tower of Power? Consider this: Though his primary residence is California, Secretary of the Treasure-designate Steven Mnuchin remains the owner of a duplex there. And ten floors above him in a triplex penthouse lives the cooperative’s president, George David, former chairman and CEO of defense contractor United Technologies, which owns Carrier, the air-conditioning giant that yesterday agreed to keep jobs in the United States. Might the neighbors have facilitated that deal in a little chat in the elevator or the basement gym?
