We have worse postal services in our region. They do not have hard budget constraints, so they keep going. But the future looks bleak for those that do have hard budget constraints: Mail volume has plummeted with the rise of e-mail, electronic bill-paying and a Web that makes everything from fashion catalogs to news instantly available. The system will handle an estimated 167 billion pieces of mail this fiscal year, down 22 percent from five years ago. It’s difficult to imagine that trend reversing, and pessimistic projections suggest that volume could plunge to 118 billion pieces by 2020.
