Let you in on a little secret EVERY INTELLIGENCE agency on the planet gets their mail delivered here from any and all sources. They go to substantial expense to do that ~
You are both engaging in hyperbole. USPS does lose a lot of mail with misdeliveries, and the USPS has thieves working for it as the links prove. USPS also has a great many honest and hardworking employees. It’s true a lost wallet is safe in the post office. Family and friends working at the post office talk about these things quite often. One of the family lost his wallet with $700 in it when it somehow fell into a batch of mail. The USPS workers at the sort facility found and returned it. Nonetheless, crooked postmasters and letter carriers were fired for major crimes, as the $250,000 theft of charity monies demonstrates.
The reputation of the USPS is not in trouble so much by the few felons who have worked for it as it is the spectacularly incompetent management. Ever since the management and supervisors began to be paid better compensation and bonuses for so-called improvements in productivity reports and annual projections, the work environment became extremely toxic and the true productivity has plummeted. The USPS had wasted vast sums of monies on automation, and the automation was incompetently planned and implented. The end result has been ever increasing costs for postage, ever decreasing mail volumes due to higher postage and technological alternatives, massive misdeliveries of mailpieces due to improper sorting by misused automation methods, managerial gaming of the bonuses through abuse of the labor force, and sheer arrogance and stupidity against workers and postal customers. The U.S. Post Office more than a century ago with the technologies of its day picked up and delivered mail up to six times per day. Now the USPS is not competent emough to deliver mail a thousand feet away from its own front doors in 3 to 5 days.
One of the great jokes is how the U.S. Post Office misdelivered an entire post office. A new post office was to be built in Frankfort, Kentucky. It was one of those post offices designed to be a landmark built in beautiful marble. Unfortunately, the U.S. Post Office misdelivered the marble construction materials for the Frankfort, Kentucky Post Office to West Frankfort, Illinois instead. To remedy the problem and avoid shipping two marble post offices to West Frankfort, Illinois, the U.S. Post Office shipped the marble construction materials designed for the new West Frankfort, Illinois to Frankfort, Kentucky. Ever since I heard that story from the U.S. Post Office managemen, I always have to smile when someone gets defensive about whether or not the USPS misdelivers mail.
There are a great many great people who exercise the patience of saints while dealing with an increasingly dysfunctional USPS management. They deserve much better, and many of these folks are heroes. Unfortunately for your desire to defend their reputations, thre are a few hieves, some poor excuses for postal workers, and too many supervisory and management people who are grossly incompetent, lacking in commonsense, and lacking in common decency. This problem was recently highlighted in a news story about a USPS letter carrier who stepped over the body of a customer onhis front porch to deliver the mail in the mailbox beside the front door. The customer had suffered a medical emergency the night before and collapsed unconcious on the steps at his front door while trying to get help. The man was still alive the next day when the letter carrier stepped over him without bothering to help or reporting the emergency. If the letter carrier had used commonsense and common decency, the paramedics could have saved his life.
The USPS has some very great people working for it, but they cannot do their jobs properly because their management cannot handle the responsibilities.
