It’s finally happening: The U.S. Postal Service is expected to announce a new plan to cut Saturday mail delivery by August, reports the NYT.These plans have been floated by the USPS for some time now as a solution to the agency’s chronic financial woes, but nothing has happened yet because of the need for congressional approval for such a move. Thus far, Congress has given no indication that it intends to give that approval, so it’s not clear exactly what the Postal Service’s plans are, although it’s possible it knows something the rest of us don’t.Congress should take the USPS up on its offer to change, if it hasn’t done so already behind closed doors. Ending Saturday mail delivery won’t solve the USPS’s problems on its own, but it’s a step in the right direction for an agency that desperately needs to get its finances back on track. The USPS has already made it abundantly clear that it wants to do this, and the American people agree: A NYT poll last year revealed that more than two-thirds of Americans would have no problem with cutting Saturday delivery.At this point, Congress is the only thing standing in the way.
