Devin Leonard warns that the USPS is nearly insolvent:
Last year its revenues were $67 billion, and its expenses were even greater. Postal service executives proudly note that if it were a private company, it would be No. 29 on the Fortune 500. The problems of the USPS are just as big. It relies on first-class mail to fund most of its operations, but first-class mail volume is steadily declining—in 2005 it fell below junk mail for the first time. This was a significant milestone. The USPS needs three pieces of junk mail to replace the profit of a vanished stamp-bearing letter.
