There’s a long and a short story to the tragic tale of Postal Service financial trouble. I’ll start with the short one. Right now, the Postal Service is being forced to pre-pay health benefits for the next 75 years during a 10-year stretch. In the past four years, those prepayments have totaled $21 billion. The agency’s deficit during that time is about $20 billion. Remove these crazy pre-payments — a requirement that no other government agency endures and no private industry would even consider — and the Postal Service would be in the black.
