Every inspection of every U.S. Post Office facility has always found duly-stamped mail in trash bins.
Postal workers have been caught throughout the U.S. burning, burying, hiding, and disposing of stamped mail rather than delivering it.
Here is yet another story of a U.S. Postman who was caught burning entire tubs of mail.
The U.S. Post Office has an unconstitutional monopoly on the delivery of 1st-class mail. The agency has EVERY POSSIBLE advantage in the marketplace: it pays no corporate, income or property taxes, it owns some of the most strategic and prestigious real estate in the country, it enjoys the power of eminent domain, etc.
Yet the Post Office cannot turn a profit and loses $5 billion annually.
