The latest Atlantic Yards puff piece arrived in mailboxes earlier this week and the cover photo is something of a head-scratcher. We’re not so sure a family in matching $75 designer polo shirts was quite who Bertha Lewis had in mind when she sold ACORN’s support to Bruce Ratner for half a million bucks and a kiss. Of course, the mailer actually got the demographic just right: The large majority of apartments in the proposed complex ARE for the polo-shirt set. Too bad that wasn’t made clear to all the low-income folks Ratner got to spend the day in line at the first public forum who actually have a snowball’s chance in hell of getting an apartment.
